@ianna I've squashed your commits and rebased them onto main in https://github.com/scikit-hep/awkward/tree/agoose77/rebase-numba-array-builder if you're happy to force push them here. I should have preserved you as the author of those commits :)

@agoose77 - do I understand correctly that some jobs get cancelled because the other architectures fail?

[agoose77]

All "matrix-jobs" (e.g. py36, py37, ...) within the same top-level job, (e.g. Linux), will be canceled if a single matrix job fails, yes. :)

If you need to turn off the fail-fast for diagnostic purposes, you can do that by changing the .github/workflows YAML in your branch—it will be fail-slow in just your branch. Just don't forget to revert it.

I added a task to this PR so that we don't forget to restore the CI configuration :)
