- exceptions.c - make_class() Added a "goto finally" so that if populate_methods() fails, the return status will be -1 (failure) instead of 0 (success). fini_exceptions(): When decref'ing the static pointers to the exception classes, clear out their dictionaries too. This breaks a cycle from class->dict->method->class and allows the classes with unbound methods to be reclaimed. This plugs a large memory leak in a common Py_Initialize()/dosomething/Py_Finalize() loop.
