--- Comment #10 from Damjan Jovanovic damjan.jov@gmail.com --- It creates 41 sockets, IPv4 and IPv6, TCP and UDP, and calls select(), WSAEventSelect() and WSAAsyncSelect() on them. Could you have found a more complex sample application lol?
The commit changed wineserver's set_socket_event(), which is called from WSAEventSelect() and WSAAsyncSelect(). We know WSAEventSelect() improved, but maybe WSAAsyncSelect() broke. Origins uses both of them.
