The problem here was that we need to know which addresses are timed-out (and not to be re-probed) much earlier than we do NS selection ATM - that's because under some circumstances it affects the depth of NS zone cut that we choose, i.e. if all addresses in a certain zone cut are "bad" in a certain sense, we need to use a zone cut closer to the root, because otherwise we'd get into a dependency cycle.
