Here are the results; basically, I've pitted 2.4.17-pre2 against
2.4.17-pre2+pre1aa1. The short story is, pre1aa1 works great for the
workload I've thrown at it (Debian 'woody'; long netfilter rules;
console-only runlevel2; exim; apache; apt-get update && apt-get -uy
dist-upgrade; ssh; one updatedb ; top). pre2 doesn't
even make it to runlevel2 (I've made two tests with the "andrea" kernel, one
in single mode for comparison with "marcelo" kernel, one in normal
multi-user mode).

Incidentally, I perceive a much better performance with 2.4.17-pre2+pre1aa1
than with 2.4.13-ac8 (Rik's VM).
