This is great news! I just gave the epoll feature a try and it seemed to work
without problems. I remember that several people tried to use epoll for their
extensions before, but all of them gave eventually up, because using anything
else than select clashed with Ruby internals' use of select for almost anything.
What did you do differently? Didn't you have any problems?
