        Intended for use by strip and rollback, so there's a common
        place for anything that has to be done before destroying history.

        This is mostly useful for saving state that is in memory and waiting
        to be flushed when the current lock is released. Because a call to
        destroyed is imminent, the repo will be invalidated causing those
        changes to stay in memory (waiting for the next unlock), or vanish
        completely.
