89	EV needs the functions pthread_atfork and clock_gettime. On most systems	92	The select backend can operate in two modes. One uses the system-provided

		110	The second very portable backend is poll(2). It does not exist on windows
		111	and various versions of Mac OS X (and on the other versions it simply
		112	doesn't work), but works basically everywhere else. It is recommended to use
		113	the default here unless you run into compile problems in ev_poll.c.
		114

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

		144
		145	Similarly to the epoll backend above, EV can take advantage of kqueue
		146	on many BSD systems (it seems to be broken on Mac OS X though, but what
		147	isn't broken on that shoddy platform... ah yes, the cash gushing by apple,
		148	selling defective software works perfectly there). Support for kqueue will
		149	be detected at runtime, with a safe fallback to other methods when it
		150	cannot be used.
