I think there should be some kind of "forced close" of the Network stack
in ex free_nsproxy() 

A netns pre-close  callback might do the job....

Any ideas how to solve this ?

I'm interested in this too; right off I don't see a workable alternative
to your suggestion. Each subsystem will have to implement that callback
and release its references on the netns.
