I think all Clint was saying is that completing the UI for base 
OpenStack deployment (Tuskar UI) is a higher priority than trying to add 
a pessimistic lock model/concurrency to any particular part of the 
existing UI.

That doesn't mean you can't work on a pessimistic locking model. It just 
means that Clint (and I) think that completing the as-yet-finished UI 
work is a more important task.

Best, and Happy New Year!
