David,
I suspect you are seeing an issue that is TCP/IP spec related, not cygwin related.
(I have squid 2.4 running on cygwin in
several locations, without any sign of the symptoms you have). However your symptoms
sound similar to those faced by Apache and
Squid with half closed connections. Due to tcp/ip's close sequence, and also to
general delay between send and acknowledgement of
receipt, you cannot know that the browser has receieved the data just because you have
written it to the socket.
Apache used a technique called lingering closes to solve this. You might consider
looking into that.
On the other hand I could be completely off base here :-]
Rob
