Good. Half the job is already done. Someone should write a book on the 2.0 kernel, and explain all the sections, and have them indexed by usage, in multiple volumes! :-) And have a appendix published for each new upgrade patch. Heheh

I really hope it will be done. I would not really mind a small performance drop, and that is why it would be #ifdef'd and optional in a make config option.
