Yeah, we'd need some kind of other object to keep the nsproxy around and
hold a reference to it.

But, it also begs other questions about how we define the namespace
boundaries vs. containers.  What if we have a normal container with
chroot'd process inside of it?  Two such processes will not share an
nsproxy because the chroot'd one has switched filesystem namespaces.

Who is to say that the "container" is represented by one process's
nsproxy more than another?
