[PATCH] Update to libaio?

Well, in this case of the ring it's an irritation to have to massage the
tracking of events into the ring format when you, say, back the aio
implementation with syslets.  If it were just queueing up results for
io_getevents(), which can lock in the kernel, we'd have more freedom.

It's a nit, don't get me wrong.

Don't ask me, ask the subsystem maintainers who have not chosen to do
this over the last N years.
