PS suspendHistory() workaround

Question

Hello,
CS SDK 1.5 are out, and while I really like them a huge lot, the Photoshop document's method suspendHistory() in ActionScript is still bugged... sigh!
Waiting for an official fix (please, please ), I've come up with a (maybe obvious) workaround, which involves HostObject (as described by Zak Nelson in this CookBook entry) and a little tweak. Basically I bounce from AS3 to JSX and back to AS3 writing my own suspendHistory function.
If someone else is having troubles as I've had, this is possibly a viable solution to adopt.
Any suggestion to make it better: obviously welcome.
In a Controller.as class I embed a Javascript file
[ Embed (source="jsx/Bounce.jsx" , mimeType=  "application/octet-stream" )]
private static var myScriptClass:Class;
Then I declare my own SuspendHistory function:
public function SuspendHistory(title:String, myFunction:String):void
   var  jsxInterface:HostObject = HostObject.getRoot(HostObject.extensions[0]);
   jsxInterface.eval( new myScriptClass ().toString());
   jsxInterface.init( this );
   jsxInterface.Bounce(title,myFunction);
where title is the only History tag that will appear in the history states list, and myFunction is... the function that I'd like to call.
On the JSX side, I've a Bounce.jsx file
var asInterface = {};
function init(wrapper)
   asInterface = wrapper;
function Bounce(title, myFunction)
   var foo = "asInterface." + myFunction;
   app.activeDocument.suspendHistory (title, foo)
The Bounce function takes the very same two parameters and bounces them back to ActionScript, calling the requested function wrapped inside a (natural working) ExtendScript suspendHistory call.
Using it in the AS3 class is straightforward, and you can even forget that there's some JSX action behind the scenes:
public function run():void
   SuspendHistory("Stuff Happening", "myASFunction()");
public function myASFunction():void
   app.activeDocument.activeLayer.duplicate();
   app.activeDocument.activeLayer.duplicate();  // really fancy stuff...
The nice part is that the function called from within suspendHistory can have parameters as well (obviously, uh)
public function run():void
   var loops:uint = 5
   SuspendHistory("Stuff Happening", "myASFunction("+loops+")");
public function myASFunction(loops:uint)
   for (var i:uint = 0; i<loops; i++)
      app.activeDocument.activeLayer.duplicate();
even though to split with quotes the function code to add the parameter isn't that elegant... but as long as it works, I'm happy - and it's better than nothing.
Cheers,
Davide
Nevertheless a fix in the CSAW libraries would be better

Forgot to mention you still have to have CS5 installed on your non-compliant laptop.  Wouldn't it be funny if this is a PS bug requiring a toggled bit to be set in order to render in 3D?
