Yeah, Microsoft's socket API is not their finest work. :)

On the MSDN Library page for WSAEventSelect()[1] we can read:

"The WSAEventSelect function automatically sets socket s to nonblocking mode,
regardless of the value of lNetworkEvents. To set socket s back to blocking
mode, it is first necessary to clear the event record associated with socket s
via a call to WSAEventSelect with lNetworkEvents set to zero and the
hEventObject parameter set to NULL. You can then call ioctlsocket or WSAIoctl
to set the socket back to blocking mode."
