Customer expressed desire that when a workflow is submitted and then a new workflow is submitted later while the 1st workflow is still running, the dispatcher/scheduler should allocate scare resources between both workflows instead of the current priority system which is mostly first-come-first-served.

The scenario, as portrayed, is if there is a 5000 sample batch running, and another user submits a 10 sample test run, the 2nd user should not have to wait for the entire 5000 sample batch to complete before their run can make any progress.
