It seems appropriate to consult python-dev on this. I thought
ValueError was for values that are valid Python objects but out of
acceptable range of the function. Errors that can only be triggered
in C code normally handled with either assert() or raise SystemError.
I think you are splitting hairs too thin by distinguishing between
stdlib and 3rd party extensions.
