It happened enough that one of the ideas we're going to explore is seeing if we can tune the x86_64 port to use the same heuristics. That way we can try to find more of these issues in our tester without having to dramatically increase s390x resourcing. This hasn't started, but I expect we'll be looking at it in the fall (it's unclear if we can just use flags or will need hackery to the x86 port, but we're happy to share whatever we find with the wider community). jeff
