I doubt there's no "one size fits all" limit. If the machines running
"recursive clobber" tests need tens of days to complete the tests. then
that limit is pretty useless to most regular animals.
So what about keeping the current value for most animals, but allowing
an override for some selected ones? I'd expect this to be much simpler
to implement, and it shouldn't require any human intervention.
