Oh, one more point: is there any reason why all of this needs to be a
single (giant) patch?  I feel like the handling of internal states
could be a separate patch from the basic patch to allow partial
aggregation and aggregate-combining, and that the latter could be
committed first if we had a reasonably final version of it.  That
seems like it would be easier from a review standpoint, and might
allow more development to proceed in parallel, too.
