Newline confusion: t/TEST sees an extra newline and gets huffy.

=head1 NAME

threads - Perl extension allowing use of interpreter based threads from perl

=head1 SYNOPSIS

use threads;

sub start_thread {
    print "Thread started\n";
}

my $thread = threads->new("start_thread","argument");

$thread->new(sub { print "I am a thread"},"argument");

$thread->join();

$thread->detach();

$thread = threads->self();

thread->tid();

=head1 DESCRIPTION

Perl 5.6 has something called interpreter threads, interpreter threads
are built on MULTIPLICITY and allows for several different perl
interpreters to run in different threads. This has been used in win32
perl to fake forks, it has also been available to people embedding
perl.

=over

=item new, function, LIST

This will create a new thread with the entry point function and give
it LIST as parameters.  It will return the corresponding threads
object.

=item $threads->join

This will wait for the corresponding thread to join. When it finishes join will return the return values of the root function.
If a thread has been detached, join will return without wait.

=item $threads->detach

Will throw away the return value from the thread and make non joinable

=item threads->self

This will return the object for the current thread.

=item $threads->tid

This will return the id of the thread.
threads->self->tid() is a quick way to get current thread id
