ADT tests periodically failing on s390x with the glib/testfilemonitor.test test case

You can see that sometimes the ADT tests fail. With retries working.

And similar. I wonder if this is due to load on the host (these tests are running in lxd) or due to unlucky random seeds. Is there a way to rerun this individual glib test case, such that I could troubleshoot this further and/or file an upstream bug report?
