I guess you are right, especially since it solves above and index.
The "physical log" solution sounds a lot simpler and more robust
(I didn't know you use PageAddItem, sounds genially simple :-)

But we should probably try to do checkpoints less frequently by default,
like every 20 min to avoid too much phys log.
