    Description

      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.
