Does this mean that the autoscaling algorithm needs refining?  The problem 
with disabling autoscaling is that the code may, in the future, fail to 
benefit from further global refinements, as old code that hard-coded sizes now 
fails to do -- and that if we don't refine the autoscaling model, other 
applications may fail to benefit.
