Shon Vella commented on LUCENE-1604:
------------------------------------

What should the transitive behavior of MultiReader, FilterReader, and 
ParallelReader be? I'm inclined to say they shouldn't pass through to their 
subordinate readers because they don't really "own" them. 

> Stop creating huge arrays to represent the absense of field norms

> Creating and keeping around huge arrays that hold a constant value is very 
> inefficient both from a heap usage standpoint and from a localility of 
> reference standpoint. It would be much more efficient to use null to 
> represent a missing norms table.
