Can't you just run your process from a simple script that loops,
restarting your process whenever it terminates:
while :
do
myprocess [args ... ]
done
Alternatively, if this process is one that you want to start when the
system boots then you could run it directly from /etc/inittab, using
"respawn" in the action field. If you do that, you'll probably want
to invoke your process via 'su' or else it will be running with root
privileges.
