Ok, now I know why I kept getting confused and not making progress

fixing tis test. There are different configurations running, and they
have subtly different backtraces. I didn't notice that the configs
changed and so I kept occilating between the two.

Now I've looked at two different configs at the same time, and so this
should be much more likely to work.
