		72	EV can use various backends with various portability issue. The select
		73	backend is the most portable and makes for a good fallback, but it can be
		74	limited to a low number of file descriptors and/or might not compile. If
		75	you have problems with compiling ev_select.c, you might try to play around
		76	with disabling it here, or forcing it to use the fd_set provided by your
		77	OS, via the next question. I highly recommend keeping it in.

		87
		88
		89	The select backend can operate in two modes. One uses the system-provided
		90	fd_set and is usually limited to 1024 file descriptors (64 on windows),
		91	the other requires your header files to define NFDBITS and declare a
		92	suitable fd_mask type. If you run into problems compiling ev_select.c, you
		93	can try forcing the use of the system fd_set here.

		107
		108
		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
		112	the default here unless you run into compile problems in ev_poll.c.

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

		140
		141
		142	Similarly to the epoll backend above, EV can take advantage of kqueue on
		143	many BSD systems. Support for kqueue will be detected at runtime, with a
		144	safe fallback to other methods when it cannot be used.
		145
		146	Note that kqueue is broken on most operating systems, so by default it
		147	won't be used on many platforms, but you can still create your own event
		148	loop with kqueue backend.
		149
		150	Here is what we know:
		151
		152	NetBSD: partially working in at least 3.1. Yeah! :)
		153	FreeBSD: broken on at least 6.2-STABLE,
		154	sockets likely work, ptys definitely don't.
		155	OpenBSD: reports indicate that it likely doesn't work
		156	(similar problems as on FreeBSD).
		157	OS X: completely, utterly broken on at least < 10.5.
