[sleepy.penguin] Epoll#wait raising Errno::EINTR

[Eric Wong <normalperson@yhbt.net>]

Who here depends on Epoll#wait raising Errno::EINTR?  I'm thinking
of changing this in the next major release, probably 3.0...

I would need to make corresponding changes in Rainbows! to deal
with this, but it wouldn't be hard.  I'm not aware of anybody using
sleepy_penguin anywhere else outside of Rainbows!, so if you have
thoughts/opinions on this, please us know!

IO.select in Ruby itself doesn't raise Errno::EINTR either, instead it
resumes with the remaining time left.  For kgio[1], I've also made the
Kgio.poll (poll(2) wrapper) match IO.select behavior.
