The work queue is thread-safe so that multiple threads can simultaneously add and remove objects from it. 
    class WorkQueue {
        LinkedList queue = new LinkedList();
        public synchronized void addWork(Object o) {
            queue.addLast(o);
            notify();
        }
        public synchronized Object getWork() throws InterruptedException {
            while (queue.isEmpty()) {
                wait();
            }
            return queue.removeFirst();
        }
    }
