The last one (I looked at all failures, glibc typically lets me find
flaky tests as they trigger so many tests), hence the caused between
quotes. And indeed a typo: glibc.

If I can help by extracting extra information from a failing run in one
of arm64 workers, don't hesitate to tell me/us what you would need.
Also, you could upload to experimental with extra debugging options (and
potentially store stuff in the artifacts) and re-trigger the britney
created runs for the pseudo excuses until you hit the failure mode.
