This looks more and more like PEP 433 :-) And honestly, when I think about it, I think that this whole mess is a solution looking for a problem. If we don't want to inherit file descriptors in child processes, the answer is simple: the subprocess module (this fact is not even mentioned in the PEP).

This is a good point. Are there any reasons (other than fd inheritance) not to use subprocess? If there are, perhaps we should try to eliminate them by improving subprocess.

Antoine.
