 =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 5005 threads 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 loosly 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 preferebly enable threads by doing
+C<use threads> as early as possible and it is not possible to enable threading
+by in an eval "";
