I broke this when I made the protocol objects be wrapped by smart pointers to appease static analysis. The Protocol base class currently VERIFY's that it's never called. So to have the best of both worlds until someone actually fixes the code to do proper de-registration, just call `exit(..)` so the smart pointers never go out of scope.
