I was looking at the pdumper and one thing I was wondering is how to use
of all the <foo>_marked_p and set_<foo>_marked functions impacts GC (and
hence) runtime performance.
I mean the fact that they're functions is perfectly fine, but the fact
that they need to test pdumper_object_p might have a measurable impact,
since I believe these operations are performed very many times per GC.
Also I don't quite understand why this is needed: IIUC the markbits of
pdump'd objects are stored elsewhere, but I don't understand why that
needs to be the case.
