Thanks Kinkie. I've had more time to look at this. I see some of the
Async stuff in comm.cc, and I'll need to study it more. I did not see
use of kqueues.

Does Squid make use of libevent or another similar library?

Does Squid support Mac OS X and OpenBSD?

Mac OS X and OpenBSD are itneresting to me because eventually an
OpenBSD appliance is one of my goals.
