Public bug reported:

We've seen this functional test failing in the gate [0] and it's due to
a bug in the helper module that was written for the functional test. [1]

The problem shows up when process_spawn is not able to find a port to
listen on and the process stays running anyways. That means that netns-
cleanup won't clean it up and this condition [2] doesn't hold (1!=0).

As per logs in the gate I can tell that it's only a bug in the
functional test but not in the module itself. I myself will submit a
patch to it right now.
