title: How can I save multiple documents concurrently in Mongoose/Node.js?
body: <p>At the moment I use save to add a single document.  Suppose I have an array of documents that I wish to store as single objects.  Is there a way of adding them all with a single function call and then getting a single callback when it is done?  I could add all the documents individually but managing the callbacks to work out when everything is done would be problematic.</p>
