    Processing proc stat files with more than 44 entries
    
    A long-standing arm and stem bug is that it checks if '/proc/<pid>/stat'
    contains exactly 44 elements and, if not, refuses to parse it. This is a
    mistake, stat files may have more entries depending on the platform. Changing
    the check to account for this.
