(You almost certainly already know this.  But for the benefit of those
who don't:)

Linux is one such, and thus the sticky bit has no effect on
non-directory files.  When applied to directories, it implements the 
sticky bit's _other_ traditional function, causing files within to be
renameable/modifiable/erasable only by file owner, directory owner, and 
the superuser.
