[issue42969] pthread_exit & PyThread_exit_thread from PyEval_RestoreThread etc. are harmful

See also a discussion about the usefulness of daemon threads:

I'm more in favor of deprecating daemon threads (in any interpreter, not only in subinterpreters). The current implementation is too fragile. There are still corner cases like the one described in this issue.
