The background thread needs to do something to wake up the main runloop after it adds an object to the array. Calling -performSelectorOnMainThread: would be an ideal way to do this. If you do that, you may not even need to use an array to queue the objects; instead just pass each object to the main thread as the parameter to that perform.
