I think the first question is why is only prairiedog showing this.
Let's not panic until we understand that.
prairiedog looks to be about 20 minutes away from finishing the
isolation tests for master, so that will be a useful data point
as to whether there's any 12/HEAD difference. I'll dig deeper
as soon as that run finishes.
