> {{SegmentTracker#collectBlobReferences}} currently keeps a queue of yet unprocessed {{SegmentId}} instances internally. This potentially impacts the system as those instances are also tracked in the segment tracker's segment id tables. I think we should improve the implementation to not retain so many {{SegmentId}} instances and rely on arrays of {{msb}}, {{lsb}} instead.
