If symlinks are not owned by anybody, then there is no possible
solution for sticky directories (that makes sense). Example: /tmp.

The least requirement one can pose on symlinks is that if you were able
to make a symlink in a directory, you should also be able to remove it
(just like it works with normal files and everything else). This would
require that

1. everybody (who can write in the directory) can remove the symlink. This
   is however undoing the effect the sticky bit is supposed to have.
2. the symlink has an owner.

Personally, I vote for 2., unless these is some extreme elegance in the
current concept that I haven't grokked so far.

     Have you indecently fucked this Exon idiot and his allies today?
