we do something similar in our startup script (though I cannot claim credit 
for this bash bashing). note success() and failure() are redhat-isms 

        # manual callout for cfagent; let it only run for upto 2min
        echo -n "cfagent execute: "
        /usr/sbin/cfagent -q > /dev/null 2>&1 &
        RETVAL=$?; subpid=$!
        if [ $RETVAL -eq 0 ]; then
            maxtime=120
            while kill -n 0 $subpid 2> /dev/null; do
                if [ "$maxtime" -lt 1 ]; then
                    kill -n 9 $subpid 2> /dev/null
                    failure "cfagent boot timeout"
                    RETVAL=1
                    break
                fi
                sleep 1
                maxtime=$((maxtime-1))
            done
            kill -n 0 $subpid 2> /dev/null || [ "$maxtime" -gt 0 ] && \
                                        success "cfagent boottime execute"

The assumption is that a reasonable cfengine run will never take two minutes
to complete.
