Re: DDD correctly emulated by HHH is correctly rejected as non-halting.

 Unneeded complexity. It is equivalent to:
        int main()
       {
         return HHH(main);
       }
 

  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.

 However, each of those instances has the same sequence of instructions
that the x86 language specifies the same operational meaning.
