I was surprised that I couldn't get this to work, because to me it
seemed like the sort of thing that *should* be possible to do.

Indeed, it is, and I made a couple of mistakes in writing the workflow
file:

  - The expression for 'skip-in-progress' needed to be enclosed in
    '${{}}' markers.

  - It also needed to take into account the job name (and matrix
    information!) where relevant. And here we can't just use
    ${{github.job}}, since that is only available inside of the job
    steps.

To the last bullet point there, we unfortunately have to copy and paste
the job name, which seems like a limitation of the Actions workflow
parser to me.

I posted an alternative approach to this patch in [1], and I would be
very curious to hear your thoughts, if you have time!

Thanks,
Taylor
