> The {{HistoryFileManager.mkdir()}} code handles the path existing simply by
> logging that the dir exists, and returning for everything else to work.
> There's a big assumption there: that the path resolves to a directory. A
> check needs to be made that this assumption is valid -throwing some IOE
> subclass if it's just a file
