hum... It is seems to be almost working, but, the fluctuation still remains. is it due to progress of jiffies ?

in nuse-bootp.c,

        for (;;) {
                if (poll(x, 1, 1) == 0) {
                        printf("1sec timeout %ld\n", time (NULL));
                        fflush(stdout);

then

<6>device eth1 entered promiscuous mode
sending bootp request for eth1.
waiting bootp reply
1sec timeout 1419331625
1sec timeout 1419331626
1sec timeout 1419331626
1sec timeout 1419331627
1sec timeout 1419331627
1sec timeout 1419331627

1sec timeout 1419331635
