Hugh,
Most excellent reply. What I found intersting is that the system iteslf, whether through intentional design or by product of abuse, starting shutting down, or at least becoming unstable enough that anyone paying attention might notice. I have not been able to get my system unstable with the things I do, and your testing might help folks get beyond "I was doing some stuff on the phone, saw the temp go to 105F and now I am gonna unroot and go back to stock".
And, get your butt of the road, driving cross country while playing a game, at the wheel, you should be ashamed of yourself

I think some folks loose track of this oc'ing to the extent that a maximum scenario may in no way shape or form relate to their partular use of the phone. In your testing, "stuff" stopped working. This is what I might call a "clue" that you are taxing the system, so back off. Most interesting.
Perhaps you can give me a tutorial on Robo Defense. I tried it, and was hopelessly lost..........
