Emacs is linked. With LD_RUN_PATH set, the linker will include a
specified run-time search path in the executable.
-On some systems, Emacs can crash due to problems with dynamic
-linking. Specifically, on SGI Irix 6.5, crashes were reported with
-backtraces like this:

-('rld' is the dynamic linker.) We don't know why this
-happens, but setting the environment variable LD_BIND_NOW to 1 (which
-forces the dynamic linker to bind all shared objects early on) seems
-to work around the problem.

Please refer to the documentation of your dynamic linker for details.

-*** 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.

-auto-revert-use-notify is set to nil in global-auto-revert-mode, therefore.
