> The current implementation simply reports the difference between the repository size before cleanup to the size after cleanup. As cleanup runs concurrently to other commits, the size increase contributed by those is not accounted for. In the extreme case where cleanup cannot reclaim anything this can even result in negative values being reported. 
> We should either change the wording of the respective log message and speak of before and after sizes or adjust our calculation of reclaimed size (preferred).
