Fixed a bug in "graceful shutdown" mode (the SIGTERM handler).  When there were no shadows running, the SIGTERM handler didn't just exit, which it does now.  When there are shadows running, the handler sets MaxJobsRunning to 0, sets a flag so that the reaper exits when the last shadow has exited, and preempts the shadows.
