Perl can be built to take advantage of threads on some systems.
To do so, Configure can be run with -Dusethreads.
-Note that threading is a highly experimental feature, and
-some known race conditions still remain. If you choose to try
-it, be very sure to not actually deploy it for production
-purposes. README.threads has more details, and is required
-reading if you enable threads.
+Note that Perl built with threading support runs slightly slower
+and uses more memory than plain Perl. The current implementation
+is believed to be stable, but it is fairly new, and so should be
+treated with caution.
If this doesn't make any sense to you, just accept the default '$dflt'.

-As of 5.5.640, Perl has two different internal threading implementations,
-the 5.005 version (5005threads) and an interpreter-based version
-(ithreads) that has one interpreter per thread. Both are very
-experimental. This arrangement exists to help developers work out
-which one is better.
+Since release 5.6, Perl has had two different threading implementations,
+the newer interpreter-based version (ithreads) with one interpreter per
+thread, and the older 5.005 version (5005threads).
+The 5005threads version is effectively unmaintained and will probably be
+removed in Perl 5.10, so there should be no need to build a Perl using it
+unless needed for backwards compatibility with some existing 5.005threads
+code.
-If you're a casual user, you probably don't want interpreter-threads
-at this time. But if you do, the 'threads' module allows their use,
-and the 'Thread' module offers an interface to both 5005threads and
-ithreads (whichever has been configured).
