   Actually, we always want to max out the selectors. It is   
   the granularity that needs to give.   
      
   Until we're down to 4-bit shifts as there is no point   
   going below that. So we can reduce the number of   
   selectors if we're down to that much memory. Which   
   happens when we have 256k of memory.   
      
   So only if we have less than 256k of memory would   
   we be in a realistic position to reduce the number of   
   selectors.
