Would it be practical to assert that the VM all-visible bit is clear whenever we clear PD_ALL_VISIBLE? There may be reasons we don't already do this that I'm missing, especially during recovery when pages can be ahead of the record being replayed. It seems like a useful check if we can find the right conditions for it. Thank you! Best regards, Andrey Borodin.
