Yes that is correct. The series is just a dumb push down, no additional
improvements (except some very minor ones).  These patches
are still needed in addition, so it would be just a base for it

Also James if you use the patch and don't pull 
please regenerate it from the git tree (or tell me to send it again) -- 
i did some fixes based on feedback.
