But at least the majority of the thread related functions can be moved
to pthreads as per the old pthreads-wine patch. That should cut down on
the number of wineserver calls.

I looked at some of the windows API and I saw the extra non-POSIX
functions, like
GetProcessHandleCount etc. which make wine's life difficult.

Well I was only suggesting replacing the custom thread syscall wrappers,
where possible, with pthread calls. Doing so will be compatible with
older systems, you just will not gain much performance.

Anyway, thanks for replying, I'll get on with seeing where wine stops
working on my system.
