大神帮看下代码，为什么ManualResetEventSlim 没有锁住线程

Question

List中的N为什么会有重复？这是Framework中的bug吗？(我的电脑4核i5 7500)

 using System;

using System.Threading.Tasks;

namespace ConsoleApp
{
    class Program
    {
        //static AutoResetEvent mre = new AutoResetEvent(true);
        static ManualResetEventSlim mre = new ManualResetEventSlim(true);
        static List<string> list = new List<string>();
        static void Main(string[] args)
        {

            Task[] tasks = new Task[10000];
            for (int i = 0; i < 10000; i++)
            {
                tasks[i] = Task.Factory.StartNew(Test);
                //tasks[i].ContinueWith(t => Set());
            }

            Task.WaitAll(tasks);

            var q = from t in list
                    group t by t into g
                    where g.Count() >1
                    select new
                    {
                        g.Key,
                        Count = g.Count()
                    };

            q.ToList().ForEach((t) => Console.WriteLine(t.Key + "---" + t.Count));

            Console.WriteLine("OK");
        }

        //static void Set()
        //{
        //    mre.Set();
        //}

        static int n = 0;
        static string Test()
        {
            try
            {
                mre.Wait();
                mre.Reset();
                Interlocked.Increment(ref n);
                var s = n.ToString();
                list.Add(s);
                return s;
            }
            finally
            {
                mre.Set();
            }
        }

    }
}
