Babel nodes that lose their seqno may take up to 200 seconds to rejoin
the network; hence this test doesn't make much sense for Babel.
Once again, I have no objection if you penalise Babel for that in the
competition, but I'd be grateful if you could run a test that makes
sense for Babel in addition to the standardised test. I suggest either
ifdown/ifup of the radio interface, or shutting down and restarting the
babeld daemon cleanly (so that /var/lib/babel-state is preserved).
