	Shut down socket operations.
enum GNUNET_GenericReturnValue	GNUNET_NETWORK_socket_disable_corking (struct GNUNET_NETWORK_Handle *desc)
	Disable the "CORK" feature for communication with the given socket, forcing the OS to immediately flush the buffer on transmission instead of potentially buffering multiple messages.
