Are you sure you can't do that? Not even using Py_IsInitialized? Try to
avoid repeatedly calling Py_Initialize - won't work.

Python 2.x does not have a way to "un-initialize" an extension module
(that's a big flaw in Python design). Modules that contain global state
are likely to crash the interpreter when used by the second time. (Python
3 attempts to fix that)
