+Perl used to have two different internal threads implementations. The current
+model (available internally since 5.6, and as a user-level module since 5.8) is
+called interpreter-based implementation (ithreads), with one interpreter per
+thread, and explicit sharing of data. The (deprecated) 5.005 version
+(5005threads) has been removed for release 5.10.
The 'threads' module is for use with the ithreads implementation. The
-'Thread' module offers an interface to either 5005threads or ithreads
-(whichever has been configured).
+'Thread' module emulates the old 5005threads interface on top of the current
+ithreads model.
When using threads, perl uses a dynamically-sized buffer for some of
the thread-safe library calls, such as those in the getpw*() family.

-=head1 SYNOPSIS
-
- use Thread::Queue;
- my $q = new Thread::Queue;
- $q->enqueue("foo", "bar");
- my $foo = $q->dequeue; # The "bar" is still in the queue.
- my $foo = $q->dequeue_nb; # returns "bar", or undef if the queue was
- # empty
- my $left = $q->pending; # returns the number of items still in the queue
-
-=head1 DESCRIPTION
-
-A queue, as implemented by C<Thread::Queue> is a thread-safe data structure
-much like a list. Any number of threads can safely add elements to the end
-of the list, or remove elements from the head of the list. (Queues don't
-permit adding or removing elements from the middle of the list)
-
-=head1 FUNCTIONS AND METHODS
-
-=over 8
-
-=item new
-
-The C<new> function creates a new empty queue.
-
-=item enqueue LIST
-
-The C<enqueue> method adds a list of scalars on to the end of the queue.
-The queue will grow as needed to accomodate the list.
-
-=item dequeue
-
-The C<dequeue> method removes a scalar from the head of the queue and
-returns it. If the queue is currently empty, C<dequeue> will block the
-thread until another thread C<enqueue>s a scalar.
-
-=item dequeue_nb
-
-The C<dequeue_nb> method, like the C<dequeue> method, removes a scalar from
-the head of the queue and returns it. Unlike C<dequeue>, though,
-C<dequeue_nb> won't block if the queue is empty, instead returning
-C<undef>.
-
-=item pending
-
-The C<pending> method returns the number of items still in the queue. (If
-there can be multiple readers on the queue it's best to lock the queue
-before checking to make sure that it stays in a consistent state)

-NOTE: This documentation describes the style of threading that was

-interpreter-based threads support, also known as ithreads, and in Perl
-5.8.0 the interpeter threads became available from perl level through
-the threads and threads::shared modules (in Perl 5.6 ithreads are
-available only internally and to XS extension builders, and used
-by the Win32 port for emulating fork()). As of Perl 5.8.0, ithreads has
-become the standard threading model for Perl.
-
-As of 5.9.0, the older threading model is not supported anymore.

-Thread::Semaphore - thread-safe semaphores (5.005-threads)
-
-=head1 CAVEAT
-
-This Perl installation is using the old unsupported "5.005 threads".
-Use of the old threads model is discouraged.
-
-For the whole story about the development of threads in Perl, and why
-you should B<not> be using "old threads" unless you know what you're

-
-=head1 SYNOPSIS
-
- use Thread::Semaphore;
- my $s = new Thread::Semaphore;
- $s->up; # Also known as the semaphore V -operation.
- # The guarded section is here
- $s->down; # Also known as the semaphore P -operation.
-
- # The default semaphore value is 1.
- my $s = new Thread::Semaphore($initial_value);
- $s->up($up_value);
- $s->down($up_value);
-
-=head1 DESCRIPTION
-
-Semaphores provide a mechanism to regulate access to resources. Semaphores,
-unlike locks, aren't tied to particular scalars, and so may be used to
-control access to anything you care to use them for.
-
-Semaphores don't limit their values to zero or one, so they can be used to
-control access to some resource that may have more than one of. (For
-example, filehandles) Increment and decrement amounts aren't fixed at one
-either, so threads can reserve or return multiple resources at once.
-
-=head1 FUNCTIONS AND METHODS
-
-=over 8
-
-=item new
-
-=item new NUMBER
-
-C<new> creates a new semaphore, and initializes its count to the passed
-number. If no number is passed, the semaphore's count is set to one.
-
-=item down
-
-=item down NUMBER
-
-The C<down> method decreases the semaphore's count by the specified number,
-or one if no number has been specified. If the semaphore's count would drop
-below zero, this method will block until such time that the semaphore's
-count is equal to or larger than the amount you're C<down>ing the
-semaphore's count by.
-
-=item up
-
-=item up NUMBER
-
-The C<up> method increases the semaphore's count by the number specified,
-or one if no number's been specified. This will unblock any thread blocked
-trying to C<down> the semaphore if the C<up> raises the semaphore count
-above what the C<down>s are trying to decrement it by.

-=head1 NAME
-
-Thread::Signal - Start a thread which runs signal handlers reliably (for old code)
-
-=head1 CAVEAT
-
-For new code the use of the C<Thread::Signal> module is discouraged and
-the direct use of the C<threads> and associated modules is encouraged instead.
-
-However, there is no direct equivalent of the Thread::Signal module in the
-new implementation of threads. On the bright side: signals are now delivered
-reliably to Perl programs that do not use threads. The handling of signals
-with the new threading features is up to the underlying thread implementation
-that is being used and may therefor be less reliable.
-
-If you want to specify a thread-specific signal, you can alter the %SIG hash
-in the thread where you want to handle a signal differently from other threads.
-This at least seems to work under Linux. But there are no guarantees and your
-mileage may vary.
-
-For the whole story about the development of threads in Perl, and why you
-should B<not> be using this module unless you know what you're doing, see the
-CAVEAT of the C<Thread> module.
-
-=head1 SYNOPSIS
-
- use Thread::Signal;
-
- $SIG{HUP} = \&some_handler;
-
-=head1 DESCRIPTION
-
-The C<Thread::Signal> module starts up a special signal handler thread.
-All signals to the process are delivered to it and it runs the
-associated C<$SIG{FOO}> handlers for them. Without this module,
-signals arriving at inopportune moments (such as when perl's internals
-are in the middle of updating critical structures) cause the perl
-code of the handler to be run unsafely which can cause memory corruption
-or worse.
-
-=head1 BUGS
-
-This module changes the semantics of signal handling slightly in that
-the signal handler is run separately from the main thread (and in
-parallel with it). This means that tricks such as calling C<die> from
-a signal handler behave differently (and, in particular, can't be
-used to exit directly from a system call).
