Cool!

Compiles, boots and runs ok:

Except that I don't need to set the flag in my config file anymore I
don't see much difference. Eg. bonnie doesn't show me any significant
differences in performance oder CPU-loads. Should it?

If I encounter any problems in the next few days with it, I'll mail
them.

Bye,
