Eliminating changes

This is the one biggish change between the last working test run in GitHub,
and now. Tests are still running locally fine, an on GitHub, in the last
run, I had one job pass and another fail, both on the same OS, just 3.10
passed and 3.9 failed. The problem still to do with (as far as I can tell)
messages inside Textual and some sort of async issue.

So let's try this.
