This work aims at making the network I/O model in Squid highly efficient given the primitives available on todays OS:es.
The "select" model currently used in Squid was "state-of-the-art" when Harvest Cached (what Squid started from) was designed, but many things have improved since then, calling for a quite different I/O model which is event-driven rather than "polled" to be effective.
