 Back when this was first posted I wanted to protest the point that a
large kernel modification is necessary, since I figured you can do a
"good enough" job with just an interface to tell the kernel not to
kill the important server processes.
 Obviously I decided to let it lie, but I just discovered this can be
done without modifying the kernel at all when I happened across an
interesting line in termrc:

/rc/bin/termrc:dontkill
'^(ipconfig|factotum|mntgen|fossil|cs|dns|listen|reboot)$'

 The default cpurc doesn't use dontkill, but I suspect it could be a
big help for all-in-one servers. Figured I'd point it out as it seems
easy to miss.
 ... plus everyone can use a good scare every now and then, and what
better way than to resurrect sad commentry?
