select() is supported in older BSD-based unices.
poll() is much more efficient, but we're not using it efficiently
right now.

There are a few more efficient ways of implementing network IO,
but unfortunately the squid codebase can't take advantage of it
just yet.

When you say async-IO, Are you referring to disk or network IO?

Hey, remember - I didn't write the original squid code, I'm just
one of the guys working on it now. :-)
