> There is some slowness in instantiating a {{FileStore}} when the {{journal.log}} file
becomes large as that file is fully read line by line. As in most cases only the last line
is actually needed, I suggest to optimise for this use case. This will also positively affect
the various tools in {{oak-run}} as they will start up much slower on big repositories.
