I explained it in another mail.

We had quite a few changes we had to make (several hundred man-hours,
about half of which was the POSIX layer and the precise time routines).

No sense trying to simulate fork() -- it stinks on Win32.  The Cygwin
and PW32 implementations of fork() are dogs.  Smarter folks than us
tried it and failed miserably.  Why reinvent a broken wheel?  We use
create process and our own startup code.  Our version is competitive
with fork() on Linux for spawning tasks and in general the queries run
considerably faster.
