Even the unices that have AIO often don't seem to be very good at
it, or at least they weren't the last time I played with it.
Certainly I know Unixware used to fake it up by creating a new
thread and doing sync IO in that thread, and I think Solaris did
the same but that was a couple of years ago now so things might
be better now.
