I'm not convinced that this covers all possible use cases.
It might be all right if you have control over the signal
handler, but what if you don't?

I think it's best if the functions in the os module remain
thin wrappers that expose the OS functionality as fully and
directly as possible. Anything else should be provided
by higher-level facilities.
