Where Wizards Fear To Tread - Perl.com: One of the big new features in perl 5.8 is that we now have real working threads available to us through the threads pragma.

However, for us module authors who already have to support our modules on different versions of perl and different platforms, we now have to deal with another case: threads! This article will show you how threads relate to modules, how we can take old modules and make them thread-safe, and round off with a new module that alters perl's behavior of the "current working directory".

To run the examples I have shown here, you need perl 5.8 RC1 or later compiled with threads. On Unix, you can use Configure -Duseithreads -Dusethreads; On Win32, the default build will always have threading enabled.
