title: wait_fences: failed to receive reply: 10004003 - during application:didFinishLaunchingWithOptions:
body: <p>I am getting the "wait_fences: failed to receive reply: 10004003" during the application:didFinishLaunchingWithOptions: method.</p>
  
  <p>I have subclassed UIWindow and overridden the drawRect method which is what is causing the error.  However, I have no idea what the error is trying to tell me, why it is occurring and how to fix it.</p>
  
  <pre><code>- (BOOL) application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
  
          window_ = [[OoviumWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
          [window_ makeKeyAndVisible];
          controller_ = [[AetherController alloc] init];  
          [window_ setRootViewController:controller_];
