HHH is specified to correctly simulate a finite number
of steps of DDD. THAT IS 100% OF EVERYTHING THAT HHH
DOES FOR THE PURPOSE OF THIS THOUGHT EXPERIMENT.

void DDD()
{
   HHH(DDD);
   return;
}

The semantics of the finite string input DDD to HHH specifies
that it will continue to call HHH(DDD) in recursive simulation.
