Perl can be built to take advantage of threads on some systems.
To do so, Configure can be run with -Dusethreads.

Note that Perl built with threading support runs slightly slower

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 'n'.
