I think this looks structurally correct now, and I think it's doing
the right thing as far as parallelism is concerned. I don't see any
obvious problems in the rest of it, either, but I haven't thought
hugely deeply about the way you are doing the costing, nor have I
totally convinced myself that all of the PathTarget and setrefs stuff
is correct. But I think it's probably pretty close. I'll study it
some more next week.
