[MonoTouch] Issue with CFRunLoop still in v1.1

[José Antonio Leal Farias]

Folks,

I'm getting a new error using UIAccelerometer and CFRunLoop together  
in v1.1. Check this code:

using MonoTouch.CoreFoundation;
using MonoTouch.Foundation;
using MonoTouch.UIKit;
using System;

namespace LoopTest
{
	public static class Accelerometer
	{
		public static void SetupAccelerometer()
		{
			// Setup the accelerometer
			UIAccelerometer.SharedAccelerometer.UpdateInterval = 1/30;
			UIAccelerometer.SharedAccelerometer.Acceleration +=  
UIAccelerometerSharedAccelerometerAcceleration;			
         }

		private static void UIAccelerometerSharedAccelerometerAcceleration  
(object sender, UIAccelerometerEventArgs e)
		{
			Console.WriteLine("Move");
		}
	}
	
	[Register ("AppDelegate")]
	class Program : UIApplicationDelegate
	{	
		public override void FinishedLaunching (UIApplication app)
		{
			Accelerometer.SetupAccelerometer();
			while (true)
			{
				while(CFRunLoop.Main.RunInMode(CFRunLoop.ModeDefault,0,true) ==  
CFRunLoopExitReason.HandledSource);
				Tick();
			}
		}

		void Tick()
		{
			Console.WriteLine("Tick");
		}
		
		static void Main (string [] args)
		{
			UIApplication.Main (args,null,"AppDelegate");
		}
	}
}

My application crash all the times. It's a bug or I'm doing something  
wrong?

José.
