Perl and Threads

[Jerry]

The Perl ports offer options for "THREADS" AND "PERL_MALLOC". Example
from the perl5.18 port:

# make showconfig
{snip}
====> Exclusive OPTIONS: you can only select none or one of them
     THREADS=off: Build threaded perl
     PERL_MALLOC=off: Use Perl malloc

Is there any advantage to one or the other? I have seen ports that have
options that require a threaded perl. Why would I not want to use at
least one of the options?
