[mono-android] Why do I NOT need RunOnUIThread?

[Wally McClure]

I've been working on this simple use of the Progress Dialog.  I have everything 
working, and then it hit me that I am not using RunOnUIThread.  My code is 
below.  I put in RunOnUIThread in several places and it still works as I would 
think it would.  Is there something magical about the Progress Dialog not 
needing the RunOnUIThread to be sprinkled in?

        ProgressDialog progressDialog;
 
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
 
            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);
 
            // Get our button from the layout resource,
            // and attach an event to it
            Button button = FindViewById<Button>(Resource.Id.MyButton);
 
            button.Click += delegate {
                progressDialog = new ProgressDialog(this);
                progressDialog.SetProgressStyle(ProgressDialogStyle.Horizontal);
                progressDialog.SetMessage("Loading...");
                progressDialog.SetCancelable(true);
                progressDialog.Show();
                System.Threading.ThreadPool.QueueUserWorkItem(
                    new System.Threading.WaitCallback(ProgressProcess));
            };
        }
 
        private void ProgressProcess(object state)
        {
            while (progressDialog.Progress < 100)
            {
                RunOnUiThread(delegate{
                    progressDialog.IncrementProgressBy(1);
                });
                System.Threading.Thread.Sleep(50);
            }
            RunOnUiThread(delegate
            {
                progressDialog.Dismiss();
            });
        }
