> 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.
