------------------------------
Nicolas, do you have a patch even if it does not apply to trunk (or should I just look for it over in 0.89fb?). I was thinking we need this just yesterday. If you put up a patch, it'd be a clue on how we might do this against trunk.

looks like jgray redid the flow for the critical path. going to punt on this one & let someone else with new critical path knowledge work on it or revisit later.
