What does the namespace data structure look like? Is there any code path that tries to recursively enumerate the whole set of namespaces (for some particular kind of namespace)?
I tend to imagine that, at a minimum, there must be some code path that reclaims unreachable namespaces when the last process in them dies...

Wouldn't simple refcounting work to reclaim unreachable namespaces?
