None, and done.
It would be good to get some feedback from Kevin on whether this is a
reasonable approach, but considering that these data structures may
finish up being redesigned as part of the GSoC project[1], it may be
best to wait and see where that goes before doing anything. I'll
follow developments there, and if this patch remains relevant I'll
plan to do some more work on it including testing (possibly with the
RUBiS benchmark from Kevin and Dan's paper since it seems the most
likely to be able to really use parallelism) for PG11 CF1.
