See his other email for more detail on what he wants.
I have not heard of this before and you are correct in that we do not 
have this capacity.
I have considered giving jails the capacity to have their own 'real /' 
  i.e. have a totally different filesystem name space (not just a 
chroot). Then when the jail is removed  then namespace would 
disappear. but that's sort of different.
