Well, people are still praising this solution on forums and mailing list, and Red Hat developer, Leonard Pottering, the man behind systemd, and infamous pulseaudio, proposed another approach to this problem. On lkml.org he proposed utilizing systemd build-in feature to create named cgroup. An implemention of hist solution, for Red Hat and Ubuntu, with short description, could be view on webupd8.

This started vivid discussion in kernel world with typical response from Linus Torvalds.

Because with only one change all distributions will have the same functionality and all users will get better OS.
