I can now say with relative certainty that it isn't the same issue.
It looks related to the fact that target-async is enabled by default.
I'm still gathering evidence, but the the reproducer is a little racy;
it doesn't always fail, and doesn't always fail at the same point :-(.

Sadly, I also noticed that the "maint set target-async" command is
missing on Windows hosts :-(. So that made testing my theory a little
more difficult, and added yet more work before we can cut the 7.8
branch. But in any case, manually setting target_async_permitted
and target_async_permitted_1 (I am paranoid) to 0 allowed me to
pass my test 20 times in a row, as opposed to having it fail roughly
12-15 times.

I will create PRs and investigate further tomorrow.
