I think this is being overly cautious.  There's no way, for example, that
SetRect, SetPt, HLock, BlockMore (to name a few) will ever move memory.  

Someone once mentioned that InitGraf used to be off the list, but now is on
the list.  Sure enough, it's not mentioned in volume 1 but is mentioned in
volume 5.  But are there other calls that were made unsafe?
