Well, I don't see the cygserver as a bad thing - setup as a service,
it's no more intrusive that RPCSS, for instance.

And for the semaphores, what I was thinking was that the cygserver
allocates anonymous semaphores, handing out the handles - not that the
cygserver would be used for each and every call.
