Interaction between reservations and userlimit can result in significant ULF violation

      Description

      ULF was set to 1.0
      User was able to consume 1.4X queue capacity.
      It looks like when this application launched, it reserved about 1000 containers, each 8G each, within about 5 seconds. I think this allowed the logic in assignToUser() to allow the userlimit to be surpassed.
