Hmm, that would explain the crash at the parallel_schedule regression
suite. ipcs showed 5 semaphores, and one shm, when postmaster crashed.
serial tests do work fine. max_connections=100 also works fine.
Do you have any link where this is discussed/analyzed?

No problem.
If it's really a buggy cygserver I'll do a interim cygipc version.
I already had one, but it clashed with cygserver.
But I really want to try to debug cygserver then.
