> During the 'marking' stage the data store janitor runs over all nodes in the
> repository and updates the last modified date of any binary that is stored in
> the data store table that it finds. However, this process loads all node
> states in the repository individually which means that a separate database
> select is run for every node in the repository. This is very inefficient. We
> can improve on this manyfold by using the same strategy as is used by the
> consistency checker: we load batches of node info objects at once that
> already contain enough information to do our processing.
