STICKY FILES
       On  older  Unix  systems,  the sticky bit caused executable files to be
       hoarded in swap space.  This feature is not useful on  modern  VM  sys-
       tems, and the Linux kernel ignores the sticky bit on files.  Other ker-
       nels may use the sticky bit on files for system-defined  purposes.   On
       some systems, only the superuser can set the sticky bit on files.
