This set of failures seems to only happen on w7u-adm and w8adm, both of which
run the tests without elevated privileges. But the failures are not systematic
so it is likely there is interference from some other test. Also there have
been 5 instances in July but then none until December:
* 2022-07-14 w8adm
* 2022-07-15 w8adm
* 2022-07-18 w8adm
* 2022-07-19 w7u-adm
* 2022-07-25 w7u-adm
* 2022-12-09 w8adm
* 2022-12-12 w8adm
