        final ClusterFixture fixture = ClusterFixture.forFlatCluster(3).markNodeAsConfigRetired(1);

        NodeInfo nodeInfo = fixture.cluster.getNodeInfo(new Node(NodeType.STORAGE, 1));
        assertEquals(State.RETIRED, nodeInfo.getWantedState().getState());
    }
A non-zero crash count update, on the other hand, implies the node is suffering
further instabilities and should not clear the unstable init flag.
