> 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.
