    public static void Main()
        using (EventWaitHandle ewh = new ManualResetEvent(false))
        using (EventWaitHandle callbackDoneEvent = new ManualResetEvent(false))
                delegate {
                    Console.WriteLine("Callback fired: {0}", Thread.CurrentThread.ManagedThreadId);
                }, null, Timeout.Infinite, true);

            Console.WriteLine("Setting the event: {0}", Thread.CurrentThread.ManagedThreadId);

Setting the event: 1
Callback fired: 4
