Yeah, XP has that built in, and Vista to an even greater extent. But they
only work on (AFAIU) the demand-paged blocks, not entire files. Does the
Linux tool read an entire file, or just the parts that were paged in at
start-up? I suspect 5 seconds would be plenty to read all the login files if
the heads didn't thrash like mad.
It just seems like it could be done better. :-)
