I'm watching a WWDC video (session 105) that's talking about multitasking with iOS 4. Something interesting was just mentioned: "any GPU usage while your app is in either of the background states results in automatic termination of the app. This includes any calls to OpenGL." How does one handle this "requirement" if the ...
I'm making a relatively simple OpenGL ES based iPhone game. While testing on the iPhone 4 I've noticed that multitasking doesn't "work".

Since the ...

I have a application which I want to make multitasking ready, but the problem I have is that it does crash when it was in the background for a longer time.
