Perl can be built to take advantage of threads, on some systems.
To do so, Configure must be run with -Dusethreads.
-(See README.threads for details.)

+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
