+Subject: [PATCH] Python 3.13 fix for missing dict segfault
+
+Python 3.13 removed a safety net from PyModule_Type's tp_init slot
+that created the module's md_dict member if it was NULL.  This
+safety net was removed because, since Python 3.11, the md_dict is
+created by tp_new and is never expected to be NULL.  So, in our
+own code, we must ensure that tp_new is called before tp_init.
