I should be more precise, sorry. In my tests I used plain Wine with
staging named pipe patches applied (some trivial conflicts needed to be
resolved AFAIR). I can try it other way if you think it would be valuable.

Yes, this patchset was intended to be as small as makes sense and
PIPE_NOWAIT is not implemented in current Wine anyway. PIPE_NOWAIT
should be easy to implement on top of my patches, preferably after
patches for immediate read/write returns are in (that's one of mentioned
optimization). I expect this to be very simple then.

Thanks for the feedback.
