socket_writev_buffer() writes in a loop, using g_poll() to block. If g_poll() fails, it tries to write more before the file descriptor is ready. In theory, this could go into a tight loop. In practice, errors other than EINTR are really unlikely, and when they happen, we're probably screwed anyway, so we can just as well loop. Clean it up a bit: retry poll on EINTR, keep ignoring other errors.
