Run patch monkey in async mode

I want to implement simple html scraper into ql.io. My idea is when you write query like code below, ql.io will fetch the page, create browser like environment (JSDom), include jQuery, execute query and fetch result. But my problem is JSDom run in async mode but ql.io 's patch monkey run in sync mode, so ql.io return result before JSDom finish running. In example below, result always is blank array. Any chance to fix that?

I think because of this code:

ql.io/modules/engine/lib/engine/http.request.js

Line 414 in 3db25d6

respJson = resource.monkeyPatch['patch response']({

query

select * from www.scraper
  where url = "http://abcdef.com/xyz"
      and title = '[{"selector":"ul li a.title"}]'
      and url = '[{"selector":"ul li a.title", "prop": "href"}]';

www.scraper.ql

-- definition of www.scraper table
create table www.scraper
  on select get from "{url}"
  using patch 'www.scraper.js'
  resultset 'results'

www.scraper.js

var jsdom   = require('jsdom');
exports['parse response'] = function(args) {
    var result = [];
    // get body
    var body = '';
    _.each(args.body, function(buf) {
         body += buf.toString('UTF-8');
    });

    // create JSDom environment, include jQuery
    jsdom.env({
         html: body,
         scripts: ['http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js'],
         done: function(err, window) {
            // run CSS query using jQuery
            // jQuery(selector).each(function() { result.push($(element).text()) });
         }
    });

    // return result as new response
    return {
       type: 'application/json',
       content: JSON.stringify(result)
    }
}
