The purpose of the "for name owner" is that if an API involves any kind 
of "conversation" you do need to care about restart.

e.g. if the API is:

  int id = GetId();
  DoStuffWithId(id);

or something like that. Essentially, anytime the API is "stateful" then 
"for name owner" is probably appropriate, and anytime the API is not 
stateful then "for name owner" is needlessly annoying/inefficient.
