I dislike the idea of *always* spawning a child process, I prefer to leave it as it is, but add a recipe in the doc, or add a new helper function doing that.

Spawning a subprocess can have side effects as well, whereas the subprocess is only need if you call the function after forking which is not the most common pattern in Python.
