Hi Eugene,

This is better but there is still something wrong happening.

Here is the output I got when the test on my victim node:

laurent at frags:~/work/criu/test$ sudo ./zdtm.py run -t
zdtm/transition/maps008

So the test's output is mentioning "PASS" while zdtm.py is saying that
it fails.
I'm wondering if there are some maps008 processes still running when
zdtm is waiting for the test to end.

Cheers,
Laurent.
