> It would be nice to be able to pause (and subsequently resume) tasks that are currently
running, in order to allow tasks from higher priority jobs to execute. At present it is quite
easy for long-running tasks from low priority jobs to block a task from a newer high priority
job, and there is no way to force the execution of the high priority task without killing
the low priority jobs.
