Or, maybe it's less mysterious than that. The failure looks like we
have not waited long enough for the just-inserted row to get replicated
to node C. That wait is implemented as
$lsn = $node_a->lsn('insert');
$node_b->wait_for_catchup('node_c', 'write', $lsn);
which looks fishy ... shouldn't wait_for_catchup be told to
wait for replay of that LSN, not just write-the-WAL?
