When a cursor is opened as part of a session, its lifetime will be tied to that session. Closing or timing out of a session will kill all associated cursors. Given this, we can remove the separate cursor timeout mechanism for cursors that live as part of a session, and rely on session cleanup to handle cleanup of orphaned cursors.
