Actually, for those out there running linux, someone
(Andrew tridgell if i remember correctly)
wrote a kernel patch to completely disable symlinks in
tmp attacks.
basically it does not follow any symlinks (in directories
with the sticky bit set) if the owner of the link is different
than the owner of the target.
i think something like this should be implemented in
other OSes as well.

Luca
