Then I don't understand yet: could you explain why pdumper needs to put
the markbits elsewhere for pdump'd objects than for non-pdump'd objects?
Since the layout of the markbits was designed without thinking of the
pdumper case, I can imagine that maybe the current placement of markbits is
inconvenient for the pdumper case (tho I don't actually which part is
inconvenient).
But surely there should be a way to layout the markbits such that it's
convenient both for pdump'd and the non-pdump'd objects.
