If the scheduler dies on the qmaster, the shadow master never takes over the
qmaster/scheduler responsibilities.

To duplicate, setup a small grid with two hosts, one being the qmaster, and a
second as a shadow master.  Then, kill -9 the scheduler pid, and monitor
$SGE_ROOT/$SGE_CELL/common/act_qmaster, and note that it never fails over to
the shadow host.
