Return of the Double Responder call

This is remarkably similar (perhaps even identical) to the double responder calling bug in Flex 3.4 which was resolved in 3.4.1

Steps to reproduce:
1. Create an application like this:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/halo"
minWidth="1024" minHeight="768"
preinitialize="getByToken()"
implements="mx.rpc.IResponder">

<fx:Script>
<![CDATA[
import mx.rpc.AsyncToken;
import mx.rpc.IResponder;
import mx.rpc.http.HTTPService;

[Bindable]
private var asSvcCounter:int;
private var asSvc:HTTPService;
private var token:AsyncToken;

private function getByToken():void

{ asSvc = new HTTPService(); asSvc.resultFormat = "e4x"; asSvc.url = "xml/game-analysis.xml"; token = asSvc.send(); token.addResponder(this); }

public function result(result:Object):void

{ asSvcCounter++; }

public function fault(fault:Object):void{

}
]]
>
</fx:Script>
<s:Label text="Called:

{asSvcCounter.toString()}

times" horizontalCenter="0" verticalCenter="0" fontSize="40"/>
</s:Application>

2. Run the Application

Actual Results:
Result handler called twice , so text is shown as Called: 2 times

Expected Results:
Result Handler should only be called once, and text should show "Called: 1 times"

Workaround (if any):
