 DD emulated by HHH according to the behavior that DD
specifies cannot possibly reach its own "ret" instruction
and terminate normally.

DD does not fully specify a behaviour. The behaviour depends on HHH,
which is not a part of DD. If HHH returns 0 then DD specifies a non-
terminatingg behaviour but that is a big if.
