Two updates:

1) The test passes on master, or at least is has passed 5 times in a row
   thus far.

2) I decided to try to build 4.0.2.4 but with the alternate signal stack
   disabled. But the build got stock. Interesting enough it got stuck in
   the same place before when I was writing my original report but after
   sitting there for a few minutes it eventually kicked itself free (or
   maybe me poking around caused it to unstick). Anyways, I wrote up a
   report of what I saw:
