I tried to reproduce this by adding a specific progress test and using
permutations to
run 1000 tests per run.
This revealed that we have a leak in the jobs framework - each job
holding 7 file descriptors open until the job is deleted automatically
after 1 hour, so running many tests fail with too many open files.
These patches fix this issue:
https://gerrit.ovirt.org/#/q/topic:qemuimg-progress
After fixing this, the new tests can run, but the progress failure is
not reproduced.
So it seems that we don't this problem with these patches.
Separating the progress test is a good idea anyway.
