The symptom is that SLURM schedules lower priority jobs to run when higher priority, dependent jobs have their dependencies satisfied.  This happens because dependent jobs still have a priority of 1 when the job queue is sorted in the schedule() function.  The proposed fix forces jobs to have their priority updated when their dependencies are satisfied.

and task count that isn't an even cut.
