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

performance drop, and that is why it would be #ifdef'd and optional in a
make config option.
