// NOTE:  GameCenter does not guarantee that callback blocks will be execute on the main thread. 
// As such, your application needs to be very careful in how it handles references to view
// controllers.  If a view controller is referenced in a block that executes on a secondary queue,
// that view controller may be released (and dealloc'd) outside the main queue.  This is true
// even if the actual block is scheduled on the main thread.  In concrete terms, this code
// snippet is not safe, even though viewController is dispatching to the main queue:
//
//	[object doSomethingWithCallback:  ^()
//	{
//		dispatch_async(dispatch_get_main_queue(), ^(void)
