      // args: Array?
      //                The data to publish. Each array item is converted into an ordered
      //                arguments on the subscribed functions.
      //
      // example:
      //                Publish stuff on '/some/topic'. Anything subscribed will be called
      //                with a function signature like: function(a,b,c){ ... }

      // callback: Function
      //                The handler event. Anytime something is $.publish'ed on a
      //                subscribed channel, the callback will be called with the
      //                published array as ordered arguments.
      //
      // returns: Array
      //                A handle which can be used to unsubscribe this particular subscription.
      //
      // example:
      //        |       $.subscribe("/some/topic", function(a, b, c){ /* handle data */ });
      //
      if (!cache[topic]) {
        cache[topic] = [];

      // summary:
      //                Disconnect a subscribed function for a topic.
      // handle: Array
      //                The return value from a $.subscribe call.
      // example:
      //        |       var handle = $.subscribe("/something", function(){});
      //        |       $.unsubscribe(handle);
      var t = handle[0];
