Yeah, I thought for a minute I had skipped ahead a few pages by mistake. One minute it's all about thousands of processes or threads, and the next it talks about select/poll/epoll/kqueue without really introducing the idea properly (but other than that I thought it was great!). Incidentally, the justin.tv chat server uses one thread per cpu, and epoll for its network io, and currently scales to a little over 10,000 connections per cpu (see http://irc.justin.tv/ http://irc.justin.tv/ for other numbers). It's the most scalable irc server that I'm aware of. I keep meaning to write something up about it...
