Allocs chunks aligned on 4096, find the pointer to the
lrecord_implementation at address (object & ~4095).
4096 is an example, of course.
OK, I remember now. But this is not a reason to avoid per record
flags. You just have to store these flags in the same place where
you store the mark bit. The same algoithm can be used to access
them.
