The state of the art is improving. Trio for Python for example is much better in terms of stack traces. > Also the default state of matters is that everything is serialized in a single thread and everything waits for their predecessor, even when they are totally unrelated... I think this is a preferable default since bugs caused by pre-emptive multithreading are much harder to debug.
