Just an arbitrary example. Sometimes I get this failure

$ cat  tests/diff/mount/uuid

+A) Cannot find /dev/loop10 in /proc/mounts


So mount can't find that UUID although it was found before by
ts_uuid_by_devname, i.e. by blkid(1).

What could be the problem:
   - another test thread removed the UUID
   - invalid blkid cache
   - a bug?
