Easier to use AIO when it's available.

You can just aio_read the sockets/disk stuff as we discover what we
need, then aio_suspend in the routine that actually needs the data to
wait for it all to get there (or a timeout to occur).

Once again, you can just aio_read this stuff, then wait for it all to
finish at once, rather than wait on them one at a time.
