Catchup takeover has a higher priority than priority takeover, so we need to only schedule priority takeover after primary catchup finishes. |

As discussed yesterday, it's unclear to me if there's any real advantage in doing this, and there's a potential disadvantage of inducing two independent periods of write unavailability instead of just one. |
