About the same here, although it probably was a bit more work as we rely
heavily on some very obscure LWP semantics, and the non-preemption
ofcourse. The fun part was implementing the locking/signalling code so
that both preemptive and non-preemptive threads could use the same
LWP primitives without problems.

Someone should get a pthread compatible API for NT.
Hmm, let's try Google...

Now that looks interesting, LGPL licenced. Maybe we should help these
guys debugging it a bit, it sure beats hacking up our own preemptive lwp
implementation for Win32.
