I did not look into the order GC scans its roots so maybe this is a silly request and you'd better disregard it. Nevertheless here it is: (1) Would it be possible to tell how many objects get marked exclusively by marking from pure storage? (2) Would it be possible to tell how many objects get marked exclusively by marking from ambiguous roots, that is, due to using conservative collection? Obviously, either (1) or (2) would be incorrect wrt the other, that is, if an object gets marked from the stack and has been already marked from pure storage that object would be counted under (1). Still I think that figures we'd get here could be useful. martin
