Is it possible to fix memory leak from third-party ads?

Question

I'm getting a consistent memory leak on Playlist.com using Google DFP advertising - leaving the tab open, it consistently uses more and more memory (only when the ads are enabled).

A sample test page that reproduces the leak can be found here: http://dl.dropboxusercontent.com/u/6278910/ad-memory-leak.html.

Is there anything that can be done on our end to help mitigate the leak? Obviously shutting off the ads is not a possible solution, financially.

Edit: You can open developer tools in Chrome and try a memory timeline - every time the ads load, they use up slightly more memory.

This is possible, try to reload the iframe to clean the DOM before removing it, then add it again. See also this answer:

<a href="#">Remove</a>
<iframe src="url" />​

$('a').click(function(){
    $('iframe')[0].contentWindow.location.reload();
    setTimeout(function(){
       $('iframe').remove();
    }, 1000);

    ... add add iframe again ...
});​

Depending on how this is made there could some flickering of the adds, but it should not be major. The adds already refresh themselves after a while, so if this is done one add iframe at a time the user would not notice.
