Outside the safety of the global mutex we need to poll on file descriptors. I found epoll(2) is a convenient way to do that, although other options could replace this module in the future (such as an AioContext-based loop or glib's GMainLoop). One important feature of this small event loop implementation is that the loop can be terminated in a thread-safe way. This allows QEMU to stop the data plane thread cleanly.
