(I seem to be unable to post this comment to the code review...) In regards to the code review posted at http://gwt-code-reviews.appspot.com/1601804, I would love to see this land in 2.5, as we have some large customers who are still using IE7. And, no surprise, we're having some memory issues...
Unfortunately, when I applied this patch to our code base, part of our app failed to render. The problem seems to be in the LayoutImplIE6 class, though I'm not sure exactly what's going wrong. Clearly the DOM is generated differently, and that's expected. If someone can provide a pointer or some more details on how the layers are supposed to be used in the onAttach now vs. previously, I will try to take a look and get a better understanding of what's going wrong.
