World-writeable directories have security issues. Avoid showing them in the documentation since someone might accidentally use them in situations where they are insecure. There tend to be 3 security problems: 1. Denial of service. An adversary may be able to create the file beforehand, consume all space/inodes, etc to sabotage us. 2. Impersonation. An adversary may be able to create a listen socket and accept incoming connections that were meant for us. 3. Unauthenticated client access. An adversary may be able to connect to us if we did not set the uid/gid and permissions correctly. These can be prevented or mitigated with private /tmp, carefully setting the umask, etc but that requires special action and does not apply to all situations. Just avoid using /tmp in examples.
