I regularly use both socketpair and fork in my MSWin32 Perl apps with ActiveState perl, and both work OK, though fork can be a little fussy.

It does seem that perlport(1) says socketpair is unavailable, which seems to be incorrect. My copy of perlport(1) says fork is properly emulated on Win32, though. This is the documentation that comes with Perl 5.8.1.

It may be that socketpair is implemented in terms of IP sockets, though, which means it wouldn't help the OP. I don't recall, and don't have a copy of Windows handy to test with.
