I'm okay with this, when @clayborg and I talked about this the original 
assumption is we should do the entire memory region it's in, because with 
deduplication we will likely get multiple pointers to the same heap. I think we 
should leave this heap-region mode, and then also build a 'just save my 
objects' extension.
