fascinatingly strange observation came out of writing the latest test
(threadwrites) to do namedpipe interoperability testing.
main process: blocking-read on namedpipe.
5 threads: write to same named pipe
the writes NEVER return (this is with xp).
so that WOULD indicate that there IS a per-pipe mutex (and that there
are bugs in nt!)
