title: Am I supposed do dispose the Image property of a UIImageView to help Garbage Collector in Monotouch?
body: <p>On my quest to reduce memory usage, another question.
  I see that <code>UIImage</code> and <code>CGImage</code> might be candidates for high memory usage in my app.
  Wherever I use a UIImage, I try to wrap it in a using block to have it <code>Dispose()</code>'d as soon as possible.</p>
  
  <p>However, often the <code>UIImage</code> ends up in a <code>UIImageView.Image</code> property.
  If I remove the <code>UIIImageView</code> from its Superview, am I supposed to <code>Dispose()</code> the <code>Image</code> property before and set it to null or is this wasted typing?</p>
