I already said so. Please at least pretend to read what I wrote
before replying.
There is a big difference here between a piddling web server and a
1000-hour simulation. If the web server goes down, you reboot it,
maybe a few users are inconvenienced meanwhile, and maybe you lose
some advertising revenue. If the simulation has to be restarted,
you've lost *valuable* computing time that is not easy to replace.
There are many environments where even the possibility of the
simulation crashing due to external influence is unacceptable. I find
it sad that you resist making FreeBSD robust against such problems,
but that's your concern.
