Fuzzy Windbg stack trace doesn't make sense

I have a simple test program that causes endless waiting on a lock.

public class SyncBlock
{

}

class Program
{
    public static SyncBlock sync = new SyncBlock();

    private static void ThreadProc()
    {
        try
        {
            Monitor.Enter(sync);


       }
        catch (Exception)
        {
            //Monitor.Exit(sync);
            Console.WriteLine("3rd party code threw an exception");
        }
    }
    static void Main(string[] args)
    {
        Thread newThread = new Thread(ThreadProc);
        newThread.Start();


        Console.WriteLine("Acquiring lock");
        Monitor.Enter(sync);

        Console.WriteLine("Releasing lock");
        Monitor.Exit(sync);

    }
}

Thus, the main thread is basically blocked when trying to make Monitor.Enter (sync). If I looked at clrStack in the main thread, its output basically shows it, which makes sense, but when I try to see the native side of the stack, I expect to see some Wait for one / several types of objects, but I do not see This. Can someone explain this. Thanks
