...and only changed very seldom after a while, I would add. Because 
changing an old tuple would invalidate the optimization for the affected 
segment.

That's why this optimization can't help for inventory tables, where an 
id might correlate with time and storage location, but writing access 
doesn't correlate with storage location (segment number) and time.
