Thank you, Chris!

It's working fine under rootflags set and mount/remount options 
"noatime,notail,data=ordered".
Nothing got wrong on here due to data-logging-13.

Netscape7 dropped its load time again by 3secs of (previously 14+1), 
OpenOffice1 increased by 1sec (of average 17secs previously). To explain 
the previous state: I've only changed -pre9 to -rc1 and data-logging 
from -10(-pre9)..13(-rc1)..11(-rc1)..16(-rc1, now!) from the old patchset.

Is this possible to be reproduced on uniprocessor machines, too ?
