Yes, that's the solution.

But keep in mind that userspace also have the dup() and dup2() sys-call
which duplicate the file descriptor (within the same process) and there
is AFAIK no way to even detect that - let alone disallow it.
And after a fork(), it's more or less the same (except that the open
file descriptors belong to different processes ....).

Generally, I wonder why that is even necessary.
