title: Restarting nodejs ntwitter twitter stream with different track keywords
body: <pre><code>var twitter = require('ntwitter');
  // Configure twitter
  
  var keywords = ['hello', 'world'];
  
  twit.stream('statuses/filter', {'track':keywords.join(',')}, function(stream) {
    stream.on('data', function (data) {
      console.log(data);
    });
  
    stream.on('end', function (response) {
      console.log("\n====================================================");
      console.log("DESTROYING");
      console.log("====================================================\n");
    });
  
    setTimeout(function(){
      stream.destroy();
    }, 60000);
  });
  </code></pre>
  
  <p>I'm new to nodejs. What is the best way to stop this and start it again with but a different set of keywords.</p>
  
  <p>I can destroy() the stream and then create a new one. But is there anyway I can just change the track keywords without disconnecting?</p>
