		109	The second very portable backend is poll(2). It does not exist on windows
		110	and various versions of Mac OS X (and on the other versions it simply
		111	doesn't work), but works basically everywhere else. It is recommended to use

		125	EV by default uses select, which makes it hard to write efficient servers,
		126	especially if the number of active conencitons is much lower than the open
		127	ones. GNU/Linux systems have a more scalable method called "epoll", which
		128	EV can use. For this to work, both your kernel and glibc have to support
		129	epoll, but if you can compile it, the detection will be done at runtime,
		130	and EV will safely fall back to using select when epoll isn't available.
		131	If unsure, accept the default.

106	EOF	144	Similarly to the epoll backend above, EV can take advantage of kqueue
