Threads work very well on NT.

You've got both technical and cultural problems here. There is no fork. If
you use the Win32 extensions you can change the user id (never done this,
so don't ask me for details), but be prepared for the fact that this kind
of stuff *means* something different on NT - the models just aren't the
same. There's also less reason to need it - between NT and the typical NT
configuration, many things that would require setuid on *nix can be done by
any wazoo on Windows.

Sockets work fine. Select also works fine, but works *only* on sockets (eg
if you're selecting on the pipes returned from popen3, you've got a
problem).
