The 'sleep 2' after the setup was 'copy & paste'. I will remove it.

The bug was initially spotted in 'init_net' and when I first tried to reproduce
it with netns, I didn't succeed without the 'sleep 1'. I didn't analyzed more
deeply. In fact, when I replay the test now, it fails as expected.
Let's remove it also.
