No, I'm quite baffled myself. As I noted in an email I just sent, before
reading this one, I can't explain it, and at least in simple attempts, can't
reproduce it either. And there are animals much closer to each other than
those two...
I forced a run while writing the other email, with keep_error_whatnot, and I
just saw it failing... Looking whether there's anything interesting to glean.
Greetings,
