title: "wait_fences: failed to receive reply: 10004003"?
body: <p>I get this cryptic error the first time (and only the first time) my view is loaded due to the following line of code:</p>
  
  <pre><code>- (void)viewWillAppear:(BOOL)animated
  {
      [textField becomeFirstResponder];
  }
  </code></pre>
  
  <p>There is a noticeable (~3 – 4 second, even on the simulator) delay due to this that makes my app feel unresponsive. Does anyone know how to fix this? I can't find any documentation on it on Apple's site, or any solutions here or on Google.</p>
  
  <p>Strangely, the opposite situation happens if I put the line in <code>-viewDidAppear:</code> instead of <code>-viewWillAppear:</code>; that is, instead of printing the error only the first time the keyboard is shown and never again, the error is <em>not</em> printed the first time but every time after. This is causing a major headache for me.</p>
