[issue44887] test_input_tty hangs when run multiple times in the same process on macOS 10.15

Amazingly, excluding every other test function with a bunch of `-i` patterns still makes it hang when ran twice. On the other hand, only including the test function with `-m` works fine.

This is very weird. Looking further.

Semi-relatedly, I found BPO-26228, could reproduce it, and finished an open PR on it. While those are separate issues, I'm hoping to solve them both.
