=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.
+Perl 5.6 introduced something called interpreter threads. Interpreter
+threads are different from "5005threads" (the thread model of Perl
+5.005) by creating a new perl interpreter per thread and not sharing
+any data or state between threads.
+
+Prior to perl 5.8 this has only been available to people embedding
+perl and for emulating fork() on windows.
+
+The threads API is loosely based on the old Thread.pm API. It is very
+important to note that variables are not shared between threads, all
+variables are per default thread local. To use shared variables one
+must use threads::shared.
+
+It is also important to note that you preferably enable threads by
+doing C<use threads> as early as possible and that it is not possible
+to enable threading inside an eval ""; In particular, if you are
+intending to share variables with threads::shared, you must
+C<use threads> before you C<use threads::shared> and threads will emit
+a warning if you do it the other way around.
