Oh I found the same description yesterday though I've had no time
to test it. If your patch resolves *hang*, it may be the right solution
at least for cygwin port.
BTW I've never passed the pararell regression test without hang or
refusal(with your previous patch appiled) under my cygwin environ-
ment. I added one more connect() call after the refusal and passed
all regression test successfully. Hmm it may be a more preferable
