Someone reported it already upstream:
<https://gitlab.com/qemu-project/qemu/-/issues/2121>.  Please add a
reference to it.

How can it be missing permissions if it is sometimes working?  Perhaps
more something racy where the file hasn't been created yet.  I'd
personally rather not see emojis or comments of dubious utility ("Very
suspect") in the source.  Perhaps add a short excerpt of the error for
the next curious person.

Otherwise, LGTM, with the added reference to the upstream issue.  Thanks
for taking the time to address flaky tests!  They are a real drag when
left unchecked.
