I consider to go back to a minimal Ubuntu 8.04 and install it's rt-kernel only

upgrade. If I don't run a apt-get upgrade ever when I have that system, then
it will be production ready again. The security is not a big issue, because
the network is disabled (except when I have to be online with it).

Yes, less than a millisecond. :-) ..but I still
have to send "nosmp" to
the kernel in Grub's menu.lst-file - or the system freezes; I wasn't
aware of that when I wrote to this list yesterday - so it's still a lot
of potential for improvements;
Hmm...seems like I've been seeing that a lot lately -- people who are
getting low latency to work, at the expense of SMP. This is troubling
for me, because I was planning on soon finally upgrading my Athlon XP
based system to an AMD quad core. Is the realtime kernel always badly
behaved on a multi-CPU system with SMP enabled? That could be bad,
considering that there almost isn't any other kind of PC these days.
