Looks good. It makes sense to me that the macro name implies the argument type. |

I triggered a custom buildbot run to validate this across the fleet. |

The custom buildbots seem happy enough, so I'll give Eric some time to review if he wants and then I'll merge. |

There was a problem hiding this comment.
The approach is good. It definitely reads better. :) I only had a chance to skim through the PR. If you'd like me to dig in and verify each line (which could be valuable given the sensitivity of this code) then I'll see about that tomorrow afternoon. Otherwise LGTM.

@ericsnowcurrently @paulmon This should be an alternative fix to #12665.
Basically, any macro/function starting with
_Py_atomicnow always requires a reference to a_Py_atomicstruct, and never the extracted value.https://bugs.python.org/issue33608
