Thank you for v2!

I think I may have caused some trouble by suggesting "trap".  Now
there is a minor issue, that may still be worth addressing: when one
sends a process a signal, one expects that it will exit due to that
signal, but calling "exit" from the trap handler causes it to exit
with the specified exit code instead.  The usual way to solve that is
to change back to the signal's default handling and then re-raise the
signal.  You can do that with something like:

    for signal in 1 2 3 13 14 15; do
        trap 'delete_netns_link; trap - $signal; kill -$signal $$' $signal
    done

but I do not know whether it is worth it.

Either way,
