atexit() is too late: when Python is embeded, Py_Finalize() may be called a long time before the program does really finish. Well, I never embeded Python in another program, but it looks like some people do initialize/finalize Python more than once: http://bugs.python.org/issue11321 "9th import of module _pickle always crashes" In this issue, Python is initialized/finalized 20 times.
