title: How to use unordered bulk inserting with Mongoskin?
body: <p>I'm having trouble using Mongoskin to perform bulk inserting (MongoDB 2.6+) on Node.</p>
  
  <pre><code>var dbURI = urigoeshere;
  var db = mongo.db(dbURI, {safe:true});
  var bulk = db.collection('collection').initializeUnorderedBulkOp();
  
  for (var i = 0; i &lt; 200000; i++) {
      bulk.insert({number: i}, function() {
          console.log('bulk inserting: ', i);
      });
  }
  
  bulk.execute(function(err, result) {
      res.json('send response statement');
  }); 
  </code></pre>
  
  <p>The above code gives the following warnings/errors:</p>
  
  <pre><code>(node) warning: possible EventEmitter memory leak detected. 51 listeners added. Use emitter.setMaxListeners() to increase limit.
  TypeError: Object #&lt;SkinClass&gt; has no method 'execute'
  (node) warning: possible EventEmitter memory leak detected. 51 listeners added. Use emitter.setMaxListeners() to increase limit.
  TypeError: Object #&lt;SkinClass&gt; has no method 'execute'
  </code></pre>
  
  <p>Is it possible to use Mongoskin to perform unordered bulk operations? If so, what am I doing wrong?</p>
