Public bug reported:
The infra is currently testing linux-meta/4.4.0.41.43 which has some bug
that it freezes the testbed (nothing actually runs any more and ssh
hangs). The actual test timeout is being spotted correctly, but then it
takes another two hours until it finally trips over some cleanup
error/timeout -- this then gets counted as a tmpfail and the whole tests
runs again:
