89	EV needs the functions pthread_atfork and clock_gettime. On most systems	91	The select backend can operate in two modes. One uses the system-provided

		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.

		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.

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