Like what? The UNIX user/permission system, including the sticky bit 
used on /tmp, is supposed to protect local users against each other, but 
this is contingent on files created in /tmp using unique names (like 
what mktemp generates). There's very little else malicious people can do 
if the system is otherwise properly set up in a secure fashion, and this 
socket-in-/tmp thing sounds like a quite legitimate concern.
