There seem to be two issues at play here: - the atexit module (and its companion helper _Py_PyAtExit()) doesn't know about sub-interpreters. - PyState_FindModule() doesn't know about sub-interpreters either, because the m_index field (which records the module's index in an interpreter's module list (PyInterpreterState.modules_by_index)) is recorded in the PyModuleDef structure rather than the module instance: it is therefore global to all interpreters Having atexit work properly with sub-interpreters would require fixing these two issues AFAICT.
