So it looks like when a test is failing the harness is failing to
unmount the loopback filesystem. Kind of get a train wreck effect
after that as its unable to mount the loopback ro for other tests,
leading to lots of unresolved failures.

I suspect the loopback file is getting corrupted. Could you try saving
a copy of loopback_disk.ext2 before you run the tests, then replacing
it after the test run? You'll also need to do a "losetup -d
/dev/loop0" before copying the backup in if you don't reboot first.
