What if a library wants to ensure that it does get appropriate exceptions so that it can handle them?

* How does this work with threads? It's shared across all threads, and thread-safe (i.e. you can continue to not pass error handlers in any thread, and the thread will use either the old or the new error handler, not something inbetween - thanks to the GIL).

Right, but if different parts of an application are turning this off and on, you'll get invalid results, such as unexpected exceptions. The question isn't whether Python's internal state will be consistent, but whether applications can ensure a consistent state for themselves.
