As far as I know there's only a threaded mpm for Apache2 available on
win32. If you have to support win32 and unix your modules must certainly
be thread aware which means you can not use all functions
mod_perl-provides to you. e.g. setting the document_root is one of those
if I remember correctly. You cannot use perls "chdir", ... .

Perl with compiled threads support (used or not used) is much slower and
when new threads are started the whole memory is copied over because
there's no copy-on-write logic like there is for fork.
