NOTE: This documentation describes the style of threading that was
-available in 5.005. Perl v5.6 also has the early beginnings of
-interpreter-based threads support (which is what will be enabled by
-default when you simply ask for -Dusethreads). However, be advised
-that interpreter threads cannot as yet be created from the Perl level
-yet. If you're looking to create threads from within Perl, chances
-are you _don't_ want interpreter threads, but want the older support
-for threads described below, enabled with:
+available in Perl 5.005. Perl 5.6.0 introduced the early beginnings of
+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.
+
+If you really want the older support for threads described below,
+it is enabled with:
sh Configure -Dusethreads -Duse5005threads
+Be warned that the old 5.005 implementation of threads is known
+to be quite buggy, and unmaintained, which means that the bugs
+are there to stay. (We are not mean by not fixing the bugs:
+the bugs are just really, really, really hard to fix. Honest.)
+
The rest of this document only applies to the use5005threads style of
-threads.
+threads, and the comments on what works on which platform are highly
+obsolete and preserved here for archaeology buffs only. The
+architecture specific hints files do all the necessary option
+tweaking automatically during Configure, both for the 5.005 threads
+and for the new interpreter threads.

Support for threading is still in the highly experimental stages. There
