I think changing the default on the root_helper_daemon option is a good 
idea if everyone is setting that anyway. There are some comments in the 
code next to the option that make me wonder if there are edge cases 
where it might not be a good idea, but I don't really know the details, 
someone from the neutron team that knows more about it would have to 
speak up.

Also, I wonder if converting to privsep in the neutron agent would 
eliminate the need for this option altogether and still gain the 
performance benefits.
