Original issue's description:
> Don't measure CPU time in timing out GPU watchdog.
>
> It's possible for the main thread to hang on a GPU event or waiting for the OS, so if CPU usage is required for timing out the watchdog then it's possible it'll never time out.
>
> Just remove the code that checks for CPU time. Time lost due to suspend/resume events should be handled by the PowerMonitor, and this code seems to work on other platforms without issues.
