Could you please check the warnings here

Those are because #3854 wasn't in yet when the CI ran. :)

test_split_whitespace failed on 3.10 Linux ARM. I didn't touch that one. :)

test_split_whitespace

this fails randomly quite frequently on 3.10 (on x86 too)

[ikrommyd]

Should we perhaps run tests in arm64 windows too in CI? Or is it too much?
