I could reproduce this issue locally.

Turns out that it was faulty test timeout code in vdsm test runner. We did not
terminate a sleep child process when the tests finished, and mock was waiting
until the sleep child process terminated.

This patch should fix the issue:
https://gerrit.ovirt.org/67799

Here are successful builds:
- http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc24-x86_64/5765/console
- http://jenkins.ovirt.org/job/vdsm_master_check-patch-el7-x86_64/4155/console

Note that these builds include also make rpm and install check, since the patch
changed a makefile. This takes about 2 minutes but most patches do not trigger
this check.
