My aio patches already have a poll operation, however it acts as a one shot
operation: an async poll does not complete until the state indicates
readiness or it is cancelled. That's needed as there is a 1-1 relationship
between submitted aio operations and the space in the completion ring. Still,
it looks like it will work quite nicely as a means of accelerating exiting
poll() based servers.
