Sorry for the desinformation, now I see that there must be some othe 
things that mocp does because when I measured it I see that my initial 
observaions were false. The script is attached, plain is the newest 
ordinary kernel 2.6.37-rc7-git5, _1 file is the first run, _2 is the 
second run. Similarily the next_ files, after mounting / with the option 
in question. They show no big difference between the kernels.
