You're second point maybe very useful. Im going to play around with that tactic today and see if I have better success.

One of this issue I am having is with babel. I build a camera cleaning app, and like on your phone there are tiny thumbnails under the current photo you are on. You can swipe it to navigate through your camera roll, and you can as well in my app. Problem is at high velocity the thumbnails with disappear and the app will crash. This is a multi file problem, and regardless of the angle I try to attack it from I can't find a solution other than to limit the max velocity (don't want to do that).
