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'.
