The sticky bit hasn't done that since Virtual replaced Swap as the 
memory management mechanism.

This is from the man page from OS X... (man sticky)

      "The sticky bit has no effect on executable files. All 
optimization on
      whether text images remain resident in memory is handled by the 
kernel's
      virtual memory system."
