There is only one DDD so "DDD correctly > emulated by HHH" should simply mean DDD and nothing else. *I added this to my latest paper* Every time any HHH correctly emulates DDD it calls the x86utm operating system to create a separate process context with its own memory virtual registers and stack, thus each recursively emulated DDD is a different instance.
