epoll on squid

I finally got a test box for me to work on again. It is a single CPU
1GHz Pentium III with 2 GB RAM, stock Redhat-7.2 + linux-2.5.59.
Running squid-3.0-devel using the epoll branch and an added patch to
close connections in epoll, I was able to get 1917 requests per second
on i.cnn.net.

This is a substantial improvement over my previous test on this box with
linux-2.4.9 running squid-2.5.STABLE1. In that test I only got 1333
requests per second. Unfortunately, there are too many variables for me
to attribute the increase in performance to squid-3, the new kernel, or
the epoll patch. I will try running another test to isolate it if I
can.

The patch for closing connections in epoll is forthcoming this week.
