I honestly think it was deliberate. What class of Operating System developer ships their OS releases without 100% CODE COVERAGE? Apple do code coverage testing, surely? I mean, more than the "-warn-dead-code" args that get flung around. I can't understand how this would have gotten released into the wild if they were doing industry-standard code coverage tests. And .. if they're not doing industrial-strength code-coverage testing on their iOS/OSX release builds, thats the real news here ..
