The change in allocationStats.hpp is unrelated, is it intended for
this fix?  Aside from that, looks good to me.

mod_oop_in_space_iterate(), the only method that calls
non_clean_card_iterate() with clear != false, is unused.  Is deleting
it one of the further cleanups?  Removing it makes it easier to see
that 'clear' is not needed, so you could include it with this change.
