        {
            AsyncQueue<int> inputQueue = new AsyncQueue<int>();

            // Queue up a couple of tasks to wait for input

            Task<int> taskOne = inputQueue.DequeueAsync(cancellationSource.Token);
            Task<int> taskTwo = inputQueue.DequeueAsync();

            // Cancel the first task and then enqueue a number
            cancellationSource.Cancel();
            await inputQueue.EnqueueAsync(1);

            // Did the second task get the number?
            Assert.Equal(TaskStatus.Canceled, taskOne.Status);
