		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
		154	backend is not used by default, even when it is compiled in, and you have
		155	to request it explicitly, e.g. with LIBEV_FLAGS=64. If unsure, accept the
		156	default.

		171	The previously mentioned Linux AIO backend is experimental and will not

		173	recommended basckend, which means it will be chosen if available even when
		174	not explicitly asked for, in preference to epoll on GNU/Linux. This option
		175	is likely temporary. When unsure, accept the default.
