Lookleft,
If you would have read my post, you would have read that I followed the non-normal procedure (Engine fails to shut down) after cycling the engine master. I think cycling the engine master was a reasonable response since I had in my right seat a pilot who just came out of our training center, was on his first flight and this was the first time he ever operated the engine master in the airplane. But hey, what do I know, I only have been doing this flying thing for 34 years.
