We clearly arean't talking about the same concept. 

In my definition and experience, the end user
rarely has any notion of what a session might be and hence no
way to understand when and why to interact with the browser
to effect control of the session.

"Session" is a relationship between a user/browser and a web
application. Only the application has any knowledge of its
composition.

The user end of a session is generally represented by a single
computing system and may include multiple windows, tabs, etc.
The applicatation will range from a single instance on a
shared host up and through many hosts distributed between
physical locations.

>From the browser/user interface perspective, a 'logout'
function could mean close all windows/tabs associated with
this session identifier, flush the cache and cookies
associated with this session and notify the application
server that the logout was invoked.

I deal with many average web users and am convinced that
placing any burden on them to define the bounds of a session
would be a colossal failure.
