------------------------------------------------------------------

I guess I just don't see a net gain.  getWeight would need to be called for each request either
in the schedule method or the queue method.  Maybe I'm misunderstanding.

      was (Author: jeromatron):
    queues are only created once, but every time something is put onto the queue (i.e. every
request) a new Pair<String, Integer> would be created.  Maybe I'm misunderstanding.
 Also the getWeight functionality would need to be used every time something is put onto the
queue to determine the weight.
