- Student's display of grades will check if it has been more than 10 minutes
  since last check for content change in course.
  - If so, loncommon::needs_coursereinit() will be called to check if
    course was changed after "Big Hash" was last tied for the user's session.
  - Course will be re-initialized (or Switch Server link displayed), as needed.
- No check made for critical messages for privileged users ('mgr' priv).
