git bisect on Linux yielded this culprit change:

    bpo-21736: Set __file__ on frozen stdlib modules. (gh-28656)
```

...
Running a git bisect ritual on macOS wasn't helpful, test_importlib out of tree too often simply hangs there (going much further back).  Apparently more than one possible issue at play here.  Lets let this issue be for the Linux one.
