Looks like the issue is actually a timing issue. I have yet to track it down, but can reproduce it consistently by simply adding a NSLog() statement right before [self.connection cancel]; in - (void)cancel, then scroll through images that are canceling the requests.

I don't think my mind can grasp a thread timing issue this late, so I will look into it more in the morning.
