148Linux 4.18 introduced another event polling interface, this time using
149the Linux AIO API. While this API is far superior to epoll and almost
150rivals kqueue, it also suffers from the same issues as kqueue typically
151does: only a subset of file types are supported (as of 4.19, I have seen
152eventfd, pipes, sockets files and some devices, but no ttys). It also
153is subject arbitrary system-wide limits imposed on it. Therefore, this
154backend is not used by default, even when it is compiled in, and you have
155to request it explicitly, e.g. with LIBEV_FLAGS=64. If unsure, accept the
156default.
