+*** Emacs eats all file descriptors when using kqueue file notifications.
+See <http://debbugs.gnu.org/22814>.
+
+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.

+functions to hang.  To work around the problem, use older or newer
+versions of gnutls-cli, or use Emacs's built-in gnutls support.
