BTW, use a debug build of Python.  Some of the relevant tests set up
scenarios so excruciatingly delicate that the only reliable symptom
when they fail is triggering a C-level assert (whatever->mro != NULL
is most common).  In a release build, failure may or may not be
visible (it usually is, but sometimes an insane object can hide its
insanity temporarily in platform-specific ways).
