+*** Emacs eats all file descriptors when using kqueue file notifications.
+
+When you have a large number of buffers running auto-revert-mode, and
+Emacs is configured to use the kqueue file notification library, it
+uses an own file descriptor for every watched file. On systems with a
+small limit of file descriptors allowed per process, like OS X, you
+could run out of file descriptors. You won't be able to open new files.
+
+Set auto-revert-use-notify to nil in order to avoid this problem.
