    A rather disgusting patch that would be. The fact is, checking
    permissions on follow_link makes little to no sense. Consider
    truncate(2), for example. Will we add another intent for that? I
    really hope not.

    I'm more and more convinced, that the current behavior is the right
    one.

    Thanks,
    Miklos
