* Avoid calling ``PyType_Type.tp_traverse`` when the argument is not a
  heap-class. There is an assert that gets tripped if you are running a
  debug build (or something to do with how Fedora builds its python).
  (John Arbash Meinel, #586122)

* Flush the file handle before exiting. We were doing it at the Python
  layer, but that might not translate into the ``FILE*`` object.
  (John Arbash Meinel, #428165)

* Handle some issues when using Pyrex 0.9.8.4. It was treating
  ``<unsigned long>`` as casting the object pointer, not as a Python
  level "extract an integer". However, assignment to an ``cdef unsigned
  long`` does the right thing. (John Arbash Meinel)

* Tweak some memory performance issues (Gary Poster, #581918)
