I first proposed to deprecate the function, but Charles-François
thinks that it's unrelated to the PEP (it can be addressed later).

The function will still be available and work.

I think that the stdlib should not handle InterruptedError exception
anymore in the Python code, to simplify the code.

Why do you want the old behaviour?
