[sleepy.penguin] [PATCH 0/17] kqueue and epoll fixes

[Eric Wong <normalperson@yhbt.net>]

I'm slowly fleshing out kqueue support and also fixing some
timing-related bugs in the test suite.  kqueue support is
tested on FreeBSD 9.1

The kqueue code should also be compatible with Rubinius,
(tested against the stable libkqueue branch under Linux)

(diffstat against "master")
