This is some awesome work, Ann. It's very neat to see that all the
races we've struggled with w.r.t. the l3 scheduler has paid off. I
would definitely like to see how these results are effected by
https://review.openstack.org/#/c/305774/ but understandably 49
physical nodes are hard to come by.

Also, we should see how to best handle of the issue Ann found (and is
tracked at https://review.openstack.org/#/c/305774/). Specifically,
reproducing this should be our goal.
