All file descriptors are added to the epoll fd. Does that mean epoll
will report the same fds again after we come out of
ppoll()/a
To minimize code duplication, epoll is hooked into aio-posix's
aio_poll() instead of rolling its own. This approach also has both
compile-time and run-time switchability.
1) When QEMU starts with a small number of fds in the event loop, ppoll
is used.
2) When QEMU starts with a big number of fds,
