title: Windows Phone Mango listbox scrolling
body: <p>I created a simple application with <code>ListBox</code> and 1000 very short strings in it. (no explicit <code>ItemTemplate</code>).
  If i scroll it really fast - there are black holes(CPU cant render fast i suppose).</p>
  
  <p>At the same time if i use <code>ItemsControl</code> in <code>ScrollViewer</code> - everything is OKay.</p>
  
  <p>Why ? Can i slow down scrolling speed in <code>ListBox</code> somehow ? 
  Users can get really confused when they are to see these black holes in the screen.</p>
  
  <p><strong>Update:</strong> Reproduces on device(HTC HD7 7.10.7740). I use databinding via <code>ItemSource</code></p>
