+Checkout for non-blocking connect is difficult as systems can't agree on
+whether it is a write condition or an error. Check for both with
+poll/select and if either flag is set, use getpeername to determine if
+the socket was really connected. If it wasn't, drop it correctly from the
+poll event list as well as to not check stale event masks.
