aio is not exactly the right API either. The IO manager would have to
call aio_suspend(), and then in order to receive events from the RTS
over the special pipe we have set up, the IO manager would have to issue
its own aio_read() on this FD. And I'm not sure whether you can use
aio_suspend() to wait for network accept(), but I suspect not. There
ought to be a single way to wait for various different types of event on
