Network namespace has two referrence counters:
- count
- use_count.
The namespace is scheduled to destruction automatically when the count
becomes 0.
There are several SLAB objects with a pointer to a namespace on them.
These objects are cleaned up during namespace stop. Some of them
increment

Protocol control sockets and netlink kernel sockets should not prevent the
namespace stop request. They are initialized and disposed in a special way by
