This series adds the ability to use epoll in aio_poll() on Linux. It's switched on in a dynamic way rather than static for two reasons: 1) when the number of fds is not high enough, using epoll has little advantage; 2) when an epoll incompatible fd needs to be handled, we need to fall back. The epoll is enabled when a fd number threshold is met.
