IO.select is an expensive call, because it has to build an fd_set (large bitfield) from an array each time we invoke it.

We're just interested in IO readiness, so on Ruby 2.0+ we can use the io/wait API instead, which adds wait_readable/wait_writable to IO objects.

This doesn't make sense, there's nothing to rescue since it's not using exceptions?

If you recall from before, JRuby silently discards :exception => false on SSL sockets and still throws exceptions. I can add a comment to that effect.
