Looking at dodo's failures, it seems that while it passes

Oooh, that is indeed an interesting observation. There are enough
examples now that it's hard to dismiss it as chance, but why would
the two runs be different?
It's not deterministic.
I tested the theory that it was some other concurrent tests causing the
issue, but that didn't wash. Here's what I did:
for f in `seq 1 100`
do echo iteration = $f
meson test --suite xid_wraparound || break
done
It took until iteration 6 to get an error. I don't think my Ubuntu
instance is especially slow. e.g. "meson compile" normally takes a
handful of seconds. Maybe concurrent tests make it more likely, but they
can't be the only cause.
