It's not clear to me whether deriving from CHeapObj *requires* heap
allocation or merely permits it. I would have guessed the latter,
based on actual usage for some of these allocation classes, but there
may be some reason I haven't spotted that would make heap allocation
required. The documentation seems to me to lean towards a requires
heap allocation interpretation. But there seem to be lots of places
where different allocation is used than what is stated by the base
class, which makes me think there are problems with what we have in
this area. But that should be a completely different discussion.
