Good suggestion. I was feeling vaguely uncomfortable with that name as
well, given what the functionality ended up being. (In previous drafts
of my patch I'd given the costing function more responsibility, but
that ends up making TSMs responsible to know what nodeSamplescan.c does,
so it's wrong.) Will do.
