>
> QueryResultCache.LookupInfo ends up keeping a reference to the 
> SemanticAnalyzer from the cached query, for as long as the cached entry is in 
> the cache. We should not be keeping the SemanticAnalyzer around after the 
> query is done executing since they can hold on to quite a bit of memory.
