Currently in pv1 we call for priority takeover without concern for whether the higher priority node is caught up in replication, which can lead to unnecessary rollbacks of w:1 writes. If we avoid calling for an election due to priority takeover if we are more than X seconds repl lagged, then that in combination with the catchup period should prevent any writes from being lost during priority takeover.
