Looking at a PyPy bug

At work today we had a 90-minute session to work on open-source projects. I dug into one of the PyPy bugs, #979, and after a false trail figured out that the example code wasn't hanging indefinitely, it was just very slow. I also looked at #965, a problem detecting the encoding of an XML file, but that references the root of the problem in Python bug #13612, where I didn't make any headway before today's session was over.
