title: PerformSelector Monotouch Threading
body: <p>Using this statement calls the selector immediately instead of 6 seconds from now.</p>
  
  <pre><code>this.PerformSelector(myStartWaitForSoundSelector, null, 6.0f);
  </code></pre>
  
  <p>Does anyone know how to get this to work with a delay?</p>
  
  <p>I am using <code>thread.Sleep(6000)</code>in the function that gets called, but the entire application locks up for six seconds.</p>
  
  <p>Thanks.</p>
