library suddenly not loading on M1 mac

[logi]

I don't know if this being on macos and M1 is important, but it seems like it might be.

This minimal test fails consistantly:

If I install cython and then run pyximport.install() it works, but now we're building the library at startup which is much too slow. Also, using 0.2.7rc6 works immediately.

Same issue on M2 Mac

This problem is reproduced not only on macOS, but also on Windows (python 3.11.2, pip 23.0) and Linux (python 3.8.10, pip 20.0.2)
