Problem with tooltips and spry data using startLoadInterval

Question

I am trying to use tooltips with a dynamic table using the spry data example at the bottom of the page:
http://labs.adobe.com/technologies/spry/articles/tooltip_overview/index.html
I have it working except that it appears to have a memory leak as firefox's memory usage continues to grow.
I did notice there is a 'new' inside the onPostUpdate:function that is being called on every table update.
So after looking at the tooltip code I modified the function to:
<script type="text/javascript">
var tt1;
var observer = {onPostUpdate:function(){if(tt1 == null){tt1 = new Spry.Widget.Tooltip('tooltip','.trigger');}else{tt1.destroy(); tt1.destroy();if(tt1.checkDestroyed()) alert("destroyed");else alert("not destroyed");delete tt1; tt1 = new Spry.Widget.Tooltip('tooltip','.trigger');}}}
Spry.Data.Region.addObserver('mainRegion', observer);
</script>
The tt1.checkDestroyed() always returns false and my memory usage continues to grow.
Any help?

Thanks for the reply.  I found a way to get it to work by changing my
observer function to the following:
else{tt1.destroy();
tt1.init('.trigger', 'tooltip',
{});tt1.attachBehaviors();Spry.Widget.Tooltip.loadQueue.push(tt1);}}
Probably not very clean but it doesn’t grow memory and works correctly.
I just put it back to the old way as in the example with a
startLoadInterval(1500) :
And I am over 500MB after ~ 30 minutes where as the top code above ran with
a startLoadInterval(1500); overnight and is about ~120MB.
I am using a double repeatchildren loop to build a table with tooltips for
each cell which may affect it.
Bottom line is I have a way to make it work so I am moving forward.  If you
still want to see it I might be able to get it up on the internet and give
you a link.
Thanks,
