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. Stefan
