title: limit filter results?
body: <p>I have a game model that hasMany messages. To keep them synced in real time I use a computed property like this:</p>
  
  <pre><code>gameMessages: function () {
      var gameId, messages;
      gameId = this.get('id');
  
      return this.get('store').filter('message', function (message) {
          return (message.get('game.id') === gameId);
      });
  }.property('messages'),
  </code></pre>
  
  <p>How can I limit the amount of messages it's returning? I only want to show the 10 newest.</p>
