Sorry for the somewhat late reply. We'd prefer not to change the  
specification here and keep the requirement. We're afraid of potential  
hard to detect incompatibility bugs if you sometimes cache and sometimes  
don't. We're also not convinced that you cannot get the performance win by  
other means.
