      Description

      In my logs, testing 0.95.1 RC1, I see:

      2013-06-07 17:31:47,377 DEBUG [ip-10-20-46-44.novalocal,48569,1370640098134-BalancerChore] balancer.StochasticLoadBalancer: Could not find a better load balance plan.  Tried 3200 different configurations in 27ms, and did not find anything with a computed cost less than 25.0
      

      Ideally we'd not even try one configuration, let alone 3.2k.
