- pythunrun.c, Py_Finalize(): move the call to _Py_PrintReferences() even farther down, to just before the call to _PyObject_DebugMallocStats(). This required the following changes: - pystate.c, PyThreadState_GetDict(): changed not to raise an exception or issue a fatal error when no current thread state is available, but simply return NULL without raising an exception (ever). - object.c, Py_ReprEnter(): when PyThreadState_GetDict() returns NULL, don't raise an exception but return 0. This means that when printing a container that's recursive, printing will go on and on and on. But that shouldn't happen in the case we care about (see first bullet). - Updated Misc/NEWS and Doc/api/init.tex to reflect changes to PyThreadState_GetDict() definition.
