> CachingTokenFilter, to my surprise, puts each new AttributeSource.State onto a LinkedList.  I think it should be an ArrayList.  On large fields that get analyzed, there can be a ton of State objects to cache.
> I also observe that State is itself a linked list of other State objects.  Perhaps we could take this one step further and do parallel arrays of AttributeImpl, thereby bypassing State.
