Correct me if I am wrong. First, as I understand, it should work only if you have bash as your default shell. So you need to set it as such shell to make the solution work. Second, what effect are you talking about? It should assign cgroups according to the shell session the process was started. There could be effect if you start something heavy in a new shell session comparing to the situation when there is no such assignment, but not in the regular case. Third, it is actual mostly for multi-core systems, but our n900 has only one CPU.

Guys, if you feel an effect after applying this, are you sure it is not a placebo?
