I've regularly used the 'sgemaster' script to stop and start the sge 
master and sched daemons without any affect on jobs.  All jobs stay 
running, and all jobs stay in the queue without any problems.  However, 
if a user tries to run an sge command while sge_qmaster isn't running, 
the command will fail.
