But what does this actually do ? I'm sure it is obvious to the python hackers, but to me, this short log just describes what the patch does, not what problem it solves and why this is a good thing.
Also, doesn't this also apply to python-2.7.x (maybe with some massaging)? Whatever problem this is solving surely exists on that code line as well.
