It also doesn't fit well with the nsproxy idea.  It would be very hard
to tell which nsproxies should be shared until the entire restart has
been completed and we've been able to figure out which ones are the
same.

This is just a coding/implementation issue, but I think it does reveal a
difference in ideology between these patches and the way that the kernel
works up until now. :)
