commit    a97eed16ef8c3a481c0cd0282b9950fb4ee28a89
Author:   Tatsuo Ishii <ishii at sraoss.co.jp>
Date:     Sat Feb 13 11:23:55 2010 +0000

    Fix read_status_file so that if all nodes were marked down status,
    it is regarded that this file is bogus. This will prevent "all
    node down" syndrome.
