This patch has been improved so it only touches abc.abstractproperty.
"make test" yields the same results with and without the patch. As a
result of the review (http://bugs.python.org/review/11610/show), the
documentation was improved to make it clear that the changes are
backward compatible. The reviewer seemed satisfied and provided some
encouraging feedback, but will not be available to guide the patch to
submission. So I am soliciting for another core committer to continue
the review and hopefully apply the changes for python-3.3.

Thanks,
