Thanks a lot for your statement. This is a big relief, my line of
thinking thus is confirmed: We shall not loose physical devices.

My question is how to debug this further? Monitoring
/proc/*/ns/net* showed that the ID of the namespace is gone after
terminating my processes in the namespace. Short of adding printk() or
playing with kprobes: to the related kernel code, how can I track the
reference count or get an idea who might hold references?

Harald
