First of all, it doesn't keep spending long time CPU like that us. (max
5 seconds)  We should use not delay(9) but tsleep(9).  See man delay(9).
 
Next, I corrected it to tsleep(9).  However, protocol became 0 and
status became busy in my amd64. 
I think that it should check that we are not busy.  However, I was not
able to test because there was no time. 

Thanks,
