A queue of Object's. One can add objects to the queue, and they are later read by a QueueReader. One can create arbitrary numbers of QueueReader's for a queue, and each one receives all the Object's that are added. Only objects that have not been read by all the QueueReader's are kept. A QueueReader only receives the Object's added to the queue after the QueueReader was created.
