!CLONE_FILES can't help. copy_files() does dup_fd() in this case.
The child still inherits the files.

I think neither version is fine ;)

exit_files() is not enough too. How about the signals, reparenting?


I already forgot all details, probably I missed somethig. But it
seems to me that it is better to just export get/set affinity and
forget about all complications.
