wow, I don't even remember posting this.

This is (mostly) wrong, but I'm unsure if a pointer to another 
pointer on the stack would correctly keep its object alive(but, I 
believe this would just be a bug I think,) If the pointer was 
pointing to a pointer on the heap, then AFAICT it would keep it 
alive.
