We still have one level of nesting - the mainloop vs the AioContext
aio_pool().

After all, we still have synchronous I/O operations like bdrv_read()
where the file descriptors and BHs only execute in the AioContext
aio_poll and other mainloop concepts are suspended (iohandlers, timers,
slirp).

We need to do something about mainloop vs AioContext.  There should only
be one interface to add a file descriptor, today we have iohandler and
aio.
