Ah, I've been looking at bisecting the problem the wrong way.
I should've been bisecting the trigger condition.
If I remove the hogs from the basic_sim then the test doesn't fail.

It also explains why I haven't been seeing this more often - most of my
tests don't include hogs. Only the info tests use hogs, the rest just
use bare sims with no named lines or hogs (aka simpletons).

Does that help isolate the root cause?

Cheers,
Kent.
