OOI, what is the reason for adding these to test_trace, instead of test.test_sys_settrace?
E.g. https://github.com/python/cpython/blob/main/Lib/test/test_sys_settrace.py#L638

The expected output in test.test_sys_settrace is stricter (as it is ordered) and a clearer, IMO.

I didn't notice test.test_sys_settrace, let me check.

[iritkatriel]

test.test_sys_settrace. has some of these, maybe I can add a case or two.

Why are the tests there numbered? Can I change the numbers?
