Thank you both "Thomas" and "Sway"! I appreciate both of your responses!
I think I will give it a go. I guess it's a true that it wouldn't hurt (not being S4 specific code) and that I've got nothing to lose.
So what type of notice does it give if it prevents a Crash/Reboot (since you've seen it)? A Toast msg? Or a msg in the Notification area? A pop up right in the foreground? Etc..
