Space saving was the only reason for nsproxy to exist.

Now of course it also provides the teensiest reduction in # instructions
since every clone results in just one reference count inc for the
nsproxy rather than one for each namespace.

Yes, that's why this consolidation doesn't make sense to me.

Especially considering again that we will now have nsproxies pointing to
containers pointing to... nsproxies.
