Py_Finalize(): Reverted recent changes that tried to move the PYTHONDUMPREFS output after most teardown. Attempts to use PYTHONDUMPREFS with the Zope3 test suite died with Py_FatalError(), since _Py_PrintReferences() can end up executing arbitrary Python code (for objects that override __repr__), and that requires an intact interpreter.
