Aside: I noticed that redis/Solaris used select() instead of the fancy new "event completion framework"[1] in Solaris 10. I figured maybe the new API would be faster and I could contribute that back, so I ported to both that framework, poll(), and /dev/poll (I feel the event API just wraps /dev/poll due to the perf #s I saw, but it isn't clear) and it turned out that select() is actually faster than any of them, which struck me as a bit odd.
