The biggest reason is that FreeBSD has a rather small main thread stack
size (2 MB for 32-bit architectures and 4 MB for 64-bit architectures),
and this parameter cannot be changed without recompiling the system threads
library.  Or at least that used to be the case last time I checked, about a
year ago.

So a given Perl program that does NOT use threads will have much smaller
stack when executed in a perl compiled with threads support.  Some large
applications (amavisd-new, IIRC) had problems with that.
