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.
