But what that means? Will stream events be queued AFTER all pending NSOperations? That will block (and hang) my mechanism, because my halfway-halted operation awaits the stream event (SpaceAvailable) to continue (thus blocking the operation queue) while the event is waiting down the queue for that operation to finish… My NSOperationQueue is serial (one operation at a time) but is it blocking its dispatch_queue? I don’t know. It’s fairly easy to test, though - I think I’ll just try. Wrapping the stream event with a high-priority NSOperation won’t help either, for the same reason.
