Enhanced Upstart User Sessions
Discuss requirements with Desktop Team and others on how the existing Upstart user sessions need to be enhanced to provide suitable facilities to the desktop.
= Key Questions =
* What needs to be stored in a "session"?
(list of entities and data types)
* What interfaces are required to such sessions?
* Is there a 1-to-1 mapping between users and sessions?
* Can/should sessions persist?
* Will users be able to manipulate their own session(s)?
* What is the maximum amount of memory a session _could_ occupy?
(Allowing an arbitrary large amount of data will impact the design).

the shutdown ordering of the user session is racy & hence the whoopsie reports.
