Actually, I think it's better practice to set the sticky bit with "chmod
1777 /tmp".

>From the chmod man page:

STICKY DIRECTORIES
       When  the  sticky  bit  is set on a directory, files in that
directory may be unlinked or renamed only by root or their owner. 
Without the sticky
       bit, anyone able to write to the directory can delete or rename
files.  The sticky bit is commonly found on directories, such as  /tmp, 
that  are
       world-writable.


Regards,

Peter.
