Skill issue on my part but I don't understand how a file descriptor "ends up" in another process. My interaction with them has been as handles, so I assumed anyone who has the handle would be able to use them.

No need to solve that education problem but that's probably why I am slow to realise the point of this change. I have not dealt with the symptoms before.
