It seems that both threads are trying to update the bindings themselves, instead of just letting the main thread do that. Is that correct? If so, is there another solution than having some kind of poll/wait loop in the main thread?

Bindings are not thread-safe; Key-Value Observing notifications are posted in the thread in which they originate.

You should have your threads communicate with the main thread, so that the main thread updates the object whose attributes your controls are bound to.

One way to do this would be to use -[NSObject performSelectorOnMainThread:withObject:waitUntilDone:].
