Yes, we'll have several disjoint per-node cpu spans for a large system, but
nearby nodes *will* overlap with more distant nodes than any given node, so I
think we're covered, unless I'm misunderstanding something.

Right. And ultimately, I think we'll want the hierarchy I mentioned in the
comments, that'll cover us a little better I think.
