-EV needs the functions pthread_atfork and clock_gettime. On most systems
-you need some special libraries for this (such as -lrt and -lpthread). You can
-specify additional libraries to provide these calls now, or accept the default.
+EV by default uses select, which makes it hard to write efficient servers,
+especially if the number of active conencitons is much lower than the open
+ones. GNU/Linux systems have a more scalable method called "epoll", which
+EV can use. For this to work, both your kernel and glibc have to support
+epoll, but if you can compile it, the detection will be done at runtime,
+and EV will safely fall back to using select when epoll isn't available.
+If unsure, accept the default.

+Similarly to the epoll backend above, EV can take advantage of kqueue on
+many BSD systems (it seems to be broken on Mac OS X though). The kqueue
+backend has not been tested, however, so it is disabled by default. Please
+test (and preferably fix) the kqueue backend when you have a machine
+supporting it.  Support for kqueue will be detected at runtime, with a
+safe fallback to other methods when it cannot be used.
