I am not sure. Cfbot seems to run tests for a particular patch every
day until it fails. (Once tests failed, it seems Cfbot sleep 10 days
or so if a patch is unchanged). If CI is that unstable, we should see
random failure day by day even if the patch is unchanged.

The particular CF test I am seeing failure is "Windows - Server 2019,
VS 2019 - Meson & ninja". As far as I know there's no equivalent
animal in the buildfarm.
