It is all in ActivePerl. You can download the source code:
Besides, I would guess (and I *am* guessing, I don't know this) that the Perl
fork stuff is fairly closely tied to Perl, i.e. it may not be easy at all to
yank it out and plug it into Python.
However, I echo the Bill's and Guido's sentiments. Having a hacked
emulation of fork encourages people to use it. Once someone has their
favorite UNIX app it running on Win32 with the fake-fork they will have
little incentive to port it properly using threads. There will then be calls
to improve to Win32 fork implementation... and that is the wrong support
