It's fine in practice (spurious calls are ignored).

Yes, it's a problem. If you don't call Py_Finalize, atexit handlers, object
destructors and the like will not be called. These include destructors of file
objects (including stdout): any buffering in a still-open file opened for
writing can be lost.

Regards

Antoine.
