> {{FileStore#cleanup}} would be more efficient when getting rid of as much
> references as possibly beforehand. Excess references are contributed by the
> current {{TarWriter}} instance and segment cache in {{SegmentTracker}}.
> Those excess references turn out to be especially harmful with many
> concurrent writers continuously writing to the repository. Starting with a
> certain write load clean up will become completely blocked.
