I could be wrong (and I probably am, but we don't have any
particualrly great tools for investigating this), but I think Scott's
changes to the filter chain and caching have got rid of the big memory
leak, but the new, highly inclusive optimized SQL for getting content
which tends to pull in the world right at the start (reducing the hits
on the database, no bad thing) means that the process gets very big
rather quickly, but then doesn't get a great deal bigger after that.

I don't think it's going to slim down very much I'm afraid.
