Description

In the case where a segment store doesn't use an external datastore, running offline compaction can result in a slight increase of the overall size, due to the cleanup threshold check present in the TarReader.
I think we need to be more aggressive with GC for offline compaction (basically reduce the threshold to zero), this would give more predictable results in terms of size.
