> the cleaner works the following way:
> * it identifies obsolete directories (delta dirs ; which doesn't have open txns)
> * removes them and done
> if there are no obsolete directoris that is attributed to that there might be open txns so the request should be retried later.
> however if for some reason the directory was already cleaned - similarily it has no obsolete directories; and thus the request is retried for forever
