Not necessarily; we may be able to detect a lot of the relevant access
patterns ourselves.  Ingo has had a swap prediction algorithm for a
while, and we talked at Usenix about a number of other things we can do
to tune vm performance automatically.  2.3 ought to be a great deal
better.  madvise() may still have merit, but we really ought to be
aiming at making the vm system as self-tuning as possible.
