[Death Note] How did Light expect to get around Ryuk killing him?

Let's assume Light won in the end and killed the task force and everyone just gives up on trying to catch him.

I imagine it wouldn't take much longer for Ryuk to off him as there is no longer a game to be entertained by Surely Ryuk wouldn't just wait and let him kill random criminals unopposed for his remaining natural life. Did he have some plan for this in order to enable him to live his natural remaining life?

Ryuk has been "alive" forever for a long time. Light's entire life is a relatively short amount of time for him. It doesn't really cost him much to let Light stick around a little longer to see where it pans out. 

Light was already one of the most entertaining humans for him by a long shot and Ryuk really lucked out with him. It's like you're watching a really good show that's close to ending, but you'd rather see that same show extended albeit less interesting, than risk watching the 99.9% of other shows that that you know will probably be crap. If Ryuk changes the channel, he won't be able to change it back, so he'll spend what amounts to a couple of days for him on the current show that he likes, before going back to a life of boredom.

However, as the concept of a lifespan exists in the Death Note world, it might just be that Light's time was up, that off of that was going to happen regardless.
