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.

171The previously mentioned Linux AIO backend is experimental and will not
172be used unless requested explicitly. You can, howeer, choose to make ti a
173recommended basckend, which means it will be chosen if available even when
174not explicitly asked for, in preference to epoll on GNU/Linux. This option
175is likely temporary. When unsure, accept the default.

302Libev contains numerous internal assert() invocations to check for
303consistency and user errors. These are normally enabled, but most
304perl builds disable this error reporting mechanism by default. You
305can re-enable these asserts here. Enabling them might help you catch
306programming bugs earlier, but might cause a small slowdown. Also, failures
307will be reported by aboritng your program, instead of throwing a perl
308exception.
