Right now the atomic access fence macros in pyatomic.h are unconditional. This means that they're active even even when you "./configure --without-threads". If Python thread support is disabled, surely we don't need to ensure atomic access to variables, because there aren't any other threads to compete with. Shouldn't we add #ifdef WITH_THREAD /* current code goes here */ #else #define _Py_atomic_load_relaxed(x) (x) /* etc */ #endif ? |

I never liked the option to disable thread support. I don't think that anyone uses it but it requires many #ifdef in the code. I would prefer to drop the option. |

This sounds like additional hassle for not much gain. Agreed with Victor. |

> I never liked the option to disable thread support. I close the issue. It is not longer possible to build Python without threading support. |
