		148	Linux 4.18 introduced another event polling interface, this time using
		149	the Linux AIO API. While this API is far superior to epoll and almost
		150	rivals kqueue, it also suffers from the same issues as kqueue typically
		151	does: only a subset of file types are supported (as of 4.19, I have seen
		152	eventfd, pipes, sockets files and some devices, but no ttys). It also
		153	is subject arbitrary system-wide limits imposed on it. Therefore, this
