Thats what I meant, but as Alex pointed out I was wrong. StoreEntry only 
pulls a small bit of the cached meta stuff into the index, and that is 
counted directly in the StoreEntry object size. The rest of it is only 
pulled in when things are moved to the cache_mem space for delivery to a 
client.
