Subject: [PATCH] Fix a (correct) warning about potential uses of uninitialized
 memory in _xxsubinterpreter. Unlike newly allocated PyObject structs or
 global structs, stack-allocated structs are not initialised, and a few places
 in the code expect the _sharedexception struct data to be either NULL or
 initialised.
