Ok well if we're going to run with this set of changes then we need to assess the affect of each change and splitting them up into separate patches would be appropriate normally anyway. That will allow us to track down which particular patch causes it. That won't mean we will turn down the change based on that one result, though, it will just help us understand it better.
