  "message": "gh-144295: Fix data race in dict method lookup and global load (gh-144312)\n\nIn `_PyDict_GetMethodStackRef`, only use the fast-path unicode lookup\nwhen the dict is owned by the current thread or already marked as shared.\nThis prevents a race between the lookup and concurrent dict resizes,\nwhich may free the PyDictKeysObject (i.e., it ensures that the resize\nuses QSBR).\n\nAddress a similar issue in `_Py_dict_lookup_threadsafe_stackref` by\ncalling `ensure_shared_on_read()`.",
