> The fair scheduler allows apps to be scheduled in FIFO fashion within a
> queue. Currently, when this setting is turned on, the scheduler only allows
> one app to run at a time. While apps submitted earlier should get first
> priority for allocations, when there is space remaining, other apps should
> have a change to get at them.
