> Cleanup operation in SegmentNodeStore detects the un referenced garbage and
> clean it up. To determine the reference validity it starts with an initial
> set of SegmentId which have a live java reference.
> This works fine for simple setup but when Oak repository is used in an
> application (like Sling) where application code can create long running
> session (for observation) then such session are bound to old NodeState at
> time of startup. Such references prevent the cleanup logic to remove older
> revisions while system is running. Such revisions can only be removed via an
> offline compaction-> cleanup.
> Need to find out a way where we can _migrate_ such old NodeState references
> to newer revisions
