title: reachabilityWithHostName timeout
body: <p>I'm implementing the Reachability class to check connection status as follows:</p>
  
  <pre><code>Reachabilitty *reachability = [Reachability reachabilityWithHostName:@"apple.com"];
  Network status = [reachability currentReachabilityStatus];
  
  if(status == NotReachable){
      ...
  }else if(status == ReachableViaWifi){
      ...
  }else if(status == ReachableViaWWNA){
      ...
  }
  </code></pre>
  
  <p>It's possible to set a timeOut when I'm calling to apple.com to check connection?</p>
