Compile and run the following program:

using System;
using System.Threading;

class Test {
        static void Main ()
        {
                ThreadPool.QueueUserWorkItem (Proc);
                Thread.Sleep (1000);
                Console.WriteLine ("Wake up Main");
        }

        static void Proc (object unused)
        {
                Console.WriteLine (Thread.CurrentThread.IsBackground);
                Thread.CurrentThread.IsBackground = false;
                Console.WriteLine (Thread.CurrentThread.IsBackground);
                Thread.Sleep (10000);
                Console.WriteLine ("Wake up TP");
