Do you mind expanding on some of your statements? Especially:

Sadly, I have a half dozen different ways activities have found to explode themselves. It makes me sad!
Also, I'd imagine video ads are also quite memory intensive, so if a low-RAM device is playing one I wouldn't be surprised if Android has to kill some processes (like your activity that was sent to the background) to make space.
Perhaps you should look into what these video ads are doing and what sort of resources they eat up?
