>> A successful gst_poll_wait() doesn't always mean successful connect()
on Windows.

This statement is also true on Linux. 


connect(s, ...)

fds[0].fd = s;
fds[0].events = POLLOUT;
r = poll(&fds, 1, ...)
if (r == 0)
  goto timeout;
if (r < 0)
  goto error;
/* r (> 0) is the number of structures which have nonzero revents fields 
 * (in other words, those descriptors with events or errors reported
 */
if (fds[0].revents & (POLLERR | POLLHUP))
  goto confailed;

send (s, "Hello", ...)


Without checking revents for errors, you can write to not-connected socket,
which leads to ECONNREFUSED error.

>> What else needs to be done before this bug can be closed?

Nothing, just remove the Windows label from the comment :)
