I tend to agree with this, but I can imagine a case where a machine
is actually being asked to do more than it should. In that case, you
might decide that you want to preserve the performance on certain
tables, at the expense of the overall system. I don't even know
whether that would work; it's just the standard answer I get when I
ask Oracle guys whether Oracle's memory management is so bad that
they have to lock tables in memory. ;-)
