> The ConnManager API returns ResultSets to users but does not provide a 
> mechanism to clean up the underlying Statement that generated the ResultSet. 
> Problematically, closing the Statement will invalidate the ResultSet, so 
> these must be cleaned up in LIFO order, putting the onus on the receiver of 
> the ResultSet.
