> Every time you execute a query, and that query does not match any existing queries
> in the QueryPlanCache, that query is *always* added to the Query Plan Cache, along with
> a lot of various antlr stuff.
> There seems to be no way to control it.
> Minimally, there should be some sort of heap of query plans where the
> least used query plan is ejected when the cache reaches it max size.
> The cache size should, of course, be user configurable.
