        !            15: segments are left on the  swap device; when the program is re-in-
        !            16: voked, COHERENT  reads ``pure'' code  (text) areas from  the swap
        !            17: device  and all  other (impure)  segments  from the  file system.
        !            18: This speeds  execution of large  programs that are  executed fre-
        !            19: quently.
        !            20: 
        !            21: This strategy works well on systems that have large swap devices.
        !            22: Because overuse  of the sticky  bit would quickly  swamp the swap
