 The probler is larger: poll() is not able to block until data is ready
 
 i.e: Adding this before sendto() will not make it work.
 
         struct pollfd pfd;
 
         pfd.fd = sd;
         pfd.events = POLLOUT;
         
         if (poll(&pfd, 1, INFTIM) == -1)
                 err(1, "poll");
         if ((pfd.revents & POLLOUT) == 0)
                 warnx("poll returned %x", pfd.revents);
