Oh yes I totally forgot about the UML support! UML could definitely be doing terminal ioctls. In a funny coincidence, a totally separate codebase that I'm working on on weekends recently started doing freaky terminal stuff, and now that hangs when run as the child of something like watchexec. So, I guess I'll get back to this kunit.py question once I've debugged that other thing, I bet I'll learn something useful. I guess it's also not worth trying to fix this if we can't be sure the replacement still fixes the problem that `stty sane` was intended to fix, unless the hang turns out to be a problem for CI tooling.
