1012  *   assume that it can write since the first OUTPUT event, and no more
1013  *   OUTPUT events will be generated unless an error occurs.
1014  * GSOCK_CONNECTION:
1015  *   Connection succesfully established, for client sockets, or incoming
1016  *   client connection, for server sockets. Wait for this event (also watch
1017  *   out for GSOCK_LOST) after you issue a nonblocking GSocket_Connect() call.
1018  * GSOCK_LOST:
1019  *   The connection is lost (or a connection request failed); this could
1020  *   be due to a failure, or due to the peer closing it gracefully.
