Except that you fail to mention that you have admitted that you are NOT 
working on the Halting Problem, despite trying to use terminology 
similar to it, but having stipulated definition that are in conflict 
with computaiton theory.

Note, "keeps repeating (unless aborted)" is a misleading statement, as 
your H will ALWAYS abort this input, and thus it NEVER will "Keep 
repeating".

You don't like me pointing out the problem because you prefer to be able 
to LIE to people about what you are doing.

You work has NOTHING to do with Halting, as your H/D are not even turing 
equivalenet to their namesakes in the proof you like to mention.
