Objects in the new Emacs might have different addresses from objects in the old 
Emacs, due to address randomization.

Yes, and that's one of the problems that we should fix. It causes us to run into 
portability problems. It's still not clear that the current implementation will 
actually work on POSIXish systems. We are on (or over) the edge of portability 
here, and we need to get off.

We don't agree.
