    static void udelay(long us)
    {
        var sw = System.Diagnostics.Stopwatch.StartNew();
        long v = (us * System.Diagnostics.Stopwatch.Frequency )/ 1000000;
        while (sw.ElapsedTicks < v)
        {
        }
    }
    static void Main(string[] args)
    {
        for (int i = 0; i < 100; i++)
        {
            Console.WriteLine("" + i + " " + DateTime.Now.Second + "." + DateTime.Now.Millisecond);
            udelay(1000000);
        }
