This is on Gentoo Linux amd64, Python 3.11.4, shellingham 1.5.3 (b8ba512).

bisect blames 7bf9e76. Indeed, it seems that _get_process_mapping() was removed there.

Also, it seems that CI doesn't actually run tests, since only test env runs tests, and CI runs all the other envs that apparently only install the package.

Hello, I has got this error on ALT Linux Sisyphus (Python 3.11.4) too. Will the issue be fixed?
