Think iframes or Ajax calls or other types of situations where A User may be session-linked to more than one current thread / process. In those cases, if there is potential for simultaneous writes to a session var, then you could theoretically have a clash. If your app uses no Ajax and has no other embedded code blocks that might trigger concurrency within a session, then locking would not be needed, in theory.
