    * Even when a channel has been \"frozen\" updates to the ChannelMonitor can continue to occur

    * ChannelManager::channel_monitor_updated, so you must store the update itself along
    * with the persisted ChannelMonitor on your own local disk prior to returning a
    * TemporaryFailure. You may, of course, employ a journaling approach, storing only the
    * ChannelMonitorUpdate on disk without updating the monitor itself, replaying the journal at
    * reload-time.
    *
