gistfile1.js

(function($) {
  // eventSettings: e.g. { eventName1: 2, eventName2: 3 }
  $.fn.waitEvents = function(eventSettings, fn) {
    var key, ret = {}, evts = eventSettings,
        origEvts = $.extend(true, {}, evts);

    for(key in evts) {
      if(evts.hasOwnProperty(key)) {
        this.bind(key, function(ev) {
                          var ley;

                          evts[ev.type]--;
                          ret[ev.type] || (ret[ev.type] = []);
                          ret[ev.type].push(ev);

                          for(ley in evts) {
                            if(evts.hasOwnProperty(ley)) {
                              if(0 < evts[ley]) {
                                return;
                              }
                            }
                          }


                          fn($.extend(true, {}, ret));

                          evts = $.extend(true, {}, origEvts);
                          ret = {};
                        });
      }
    }

    return this;
  }
}(jQuery));

There should be function for "un"wait..
