Unless I get negative feedback really soon I plan to submit this later today. I've tweaked the patch slightly to be smarter about replacing the setter and the deleter together if they are the same object.

Definitely +1 on the basic patch.

Could you explain briefly the advantage of the "hack" that merges the set and del methods? Looking at the patch, I get a little nervous about this::

    @foo.setter
    def foo(self, value=None):
        if value is None:
            del self._foo
        else:
            self._foo = abs(value)

That means that c.foo = None is equivalent to del c.foo right?
