It's actually ''not'' an error to exit if all routes and children are

gone.  So exit with 0, not ORTE_ERROR_DEFAULT_EXIT_CODE (which is 1).

This fixes a race condition in the rsh launcher upon termination,
where ORTE would sometimes think that a daemon failed to launch.

This commit was SVN r26935.
