    lib/zonecut: avoid one kind of NS dependency cycles · 1fb58d76
    Vladimír Čunát authored
    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.
