> For some environments, it is desirable to have certain queues have an SLA with regards to task turnover.  (i.e., a slot will be free in X minutes and scheduled to the appropriate job)  Queues should have a 'task time limit' that would cause task attempts over this time to be killed. This leaves open the possibility that if the task was on a bad node, it could still be rescheduled up to max.task.attempt times.
