Currently mark bitmaps are stored within Chunks where two bits are provided per valid cell alignment for the smallest possible cell. However since Arenas store only objects of a paticular AllocKind the mark bitmaps can be made more compact by stroing to bits per valid cell alignment of that AllocKind.
