Just have a cron job check for "named" every minute and restart it if necessary
:-)

(Actually, that's only half in jest: if *forced* to run named on a pathetically
memory-deprived system, where other, more stateful servers were also contending
for the memory resources, I might consider this option. Or, alternatively, I might
just buy some more RAM for the box, putting it on my personal credit card if
necessary, just to embarrass the beancounters :-).
