Perhaps you're not a very technical person then. Or you have some bizarro ideas about testing new apps.
If an app is "not responding" after one hour, and it's not doing physics simulation or renders a 3D movie for Pixar, then you kill it and try again. Damn, I wouldn't even let it stay stalled for 10 minutes.
If you genuinely want to test the app (instead of only being interested in Google Sync), you'd also try how it does some other stuff, like adding some RSS feeds directly.
