Here's the code in twisted/internet/udp.py that calls sendto:

            try:
                return self.socket.sendto(datagram, addr)
            except socket.error, se:
                # [snipped; a whole bunch of error handling]

I don't know why you think that Twisted assumes that, as the code clearly
does expect to handle errors from sendto, including EINTR.
