John,
it is not because you keep posting the same numbers over and over again
(or is this your new signature?) that they will be more substantiated
(hint: cpu usage).
Just more annoying each time.
I'll remember to use reiser4 for my
90-percent-zero-files-no-need-for-proven-robustness-and-plenty-of-cpu-to-spare
boxes. Thank you.
