Just in case I haven't described the problem I see clearly enough: "Everyone" means everything (other SW) too, and if "Happy_Eyeballs" algorithms are used (see RFC 6555), this also affects systems which only have an IPv4 connection to the world, as long as IPv6 is enabled. That means it does not only affect multiuser systems and the current behaviour of kernels < 4.2 renders e.g. the private mode of most browsers somewhat useless too (in regard to protection against other SW and/or users running on the same system). That's why I vote to check out if it's possible/reasonable to backport this series to the stable kernels.
