New submission from Armin Rigo <ar...@users.sourceforge.net>:
_PyInstance_Lookup() is documented as follows:
The point of this routine is that it never calls arbitrary Python
code, so is always "safe": all it does is dict lookups.
But of course dict lookups can call arbitrary Python code. This function has
no purpose, because it's not possible to be "safe". I checked in a crasher:
