Well, they've already got a patch for that on the Python issue. It will likely be fixed in Python 3.3.
In the meanwhile, if I understand the issue correctly, it should be enough to just fix this one recursion error. So I think we should just fix issue 2899, and even if there are other recursion problems they shouldn't show up (unless we are very unlucky). We need to fix that issue anyway.
