title: iOS app doesn't go into suspension
body: <p>I've created a new project and added an infinite loop to <code>applicationDidEnterBackground</code>. </p>
  
  <pre><code>    while ( true)
  {
      NSLog(@"Running");
  }
  </code></pre>
  
  <p>The loop keps running for minutes, never ends, while according to the apple docs and my experience it should be suspended after ~5 seconds.</p>
  
  <p>Why doesn't it ?</p>
