Comment 1 for bug 2009191

The ingredients required to hit this bug are:

1. an all-proposed build (--apt-pocket=proposed with no package pinning)
2. multiple tests defined in d/t/control
3. the tests do not allow reusing the same testbed system

Condition 1. means that we don't hit the bug in tests runs triggered
by britney, as those are not all-proposed.
