title: Sending multiple goutte requests asynchronously
body: <p>This is the code I am using</p>
  
  <pre><code>require_once 'goutte.phar';
  use Goutte\Client;
  $client = new Client();
  for($i=0;$i&lt;10;$i++){
       $crawler = $client-&gt;request('GET', 'http://website.com');
       echo '&lt;p&gt;'.$crawler-&gt;filterXpath('//meta[@property="og:description"]')-&gt;attr('content').'&lt;/p&gt;';
       echo '&lt;p&gt;'.$crawler-&gt;filter('title')-&gt;text().'&lt;/p&gt;';
  }
  </code></pre>
  
  <p>This works but takes a lot of time to process? Is there any way to do it faster.</p>
