We have a small pile of sometimes-failing tests that need investigation:

• Finnegan's Wake Demo
• Heartbeat Demo
• test_destroy_configurations
• Functional suite fails when run all together with CLI tests due to background-running Ursula from previous fixtures:

        output = stdout_trap.getvalue()
>       assert not output
E       assert not "Can't learn right now: Need some nodes to start learning from.\n"
