Just to check: What happens if you rerun these tests?

Excellent question - naively, I hadn't thought of trying that. In
fact, both tests pass on every rerun. This is kind of scary except if
someone has a good explanation.
The explanation is that parallel testing is unreliable. People are working on
improving it.
I've had one example of where a test was reported to fail, but the log showed it
passed.
It makes me wonder if there are cases where a test fails, but it does not get
reported properly. That would be the most scary thing.
