> If the Cleaner does not delete any files, the compaction queue entry is
> thrown back to the queue and remains in "ready for cleaning" state.
> Problem: If 2 compactions run on the same table and enter "ready for
> cleaning" state at the same time, only one "cleaning" will remove obsolete
> files, the other entry will remain in the queue in "ready for cleaning" state.
