  Log:
  Close a race condition that doesn't really exist in -current.  When
  a resource shortage occurs, freeze our queue and then set the resource
  shortage flag while the controller data structure is locked.  The old
  code did these in the wrong order potentially allowing our interrupt
  handler to release the queue and clear the flag before the freeze
  ever occurred.
