Forgot to mention, the error that bugs me is this one:

http://jenkins.ovirt.org/job/vdsm_unit_tests_gerrit/1962/console

We had several of those today and it all seemed to stop when I set the 
core dump limit to 'unlimited' (ulimit -c). I saw that before with one 
patch but subsequent patches worked, so I did not investigate further. 
As far as I know, the problem is that the test testIsSuperUp somehow 
end up killing the jenkins slave process (if you run it manually you 
get a message that says 'killed' in the console). That test seems to 
mess with threads and processes and maybe it just identifies the slave 
process as the one to stop (just a wild guess :S).
