> Changes that are committed during a segment store compaction run will be
> compacted on top of the already compacted changes. However the compactor uses
> the wrong before state in this case. Instead of compacting against the
> compacted before state it uses the un-compacted before state. The resulting
> state will thus contain references to un-compacted state, making those not
> eligible for later clean up.
