    knotty: Implement console 'keepalive' output
    
    CI systems like jenkins and buildbot will timeout applications which haven't had console output
    in some period of time. Add 'keepalive' output to knotty which gives output every 5000s if not
    other output was made and tasks are still running. This reduces some problems encountered
    with our CI testing.
