Good point. But that would be me taking over the work of the OOM killer. It's possible for the app to hit 80% memory usage without causing OOM, when there's no other expensive process starting or demanding more memory. That's why I defer to the OOM killer. Also if the app hits 80% memory usage it's probably at its peak activity. Restart and it will quickly climb to >= 80% again. It will be restart games at peak activity, which won't be good at all.
