*** 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.
