Occasionally, with parallel jobs the mom gets stuck waiting
for all of the sister nodes to report in. If there is one
or more nodes that do not check in a job stays in a running
state forever. This fix uses the examine_all_running_jobs function
to check for jobs stuck in a JOB_SUBSTATE_PRERUN state. If they
are still in a PRERUN state on the second check the job is aborted.
