This is definitely the direction we want to go! I wonder whether our new save format should be Elf too. I'm not sure it will buy us anything much, but perhaps the dump format will be extensible enough if we define suitable extra Elf notes for the extra non-cpu state that we need. Something to think about. -- Keir
