+Subject: [PATCH] gsocket windows: check event before calling
+ WSAEnumNetworkEvents
+
+The WSAEnumNetworkEvents API is called every time the socket
+needs to be checked for status changes. Doing this in an application
+with several sockets could generate a high cpu usage since
+this call is done for each socket at each iteration of the main loop.
+Since there is also a WSAEvent that gets signaled when there is
+a change in the status of the socket, checking its status and
+calling the WSAEnumNetworkEvents API only if the event is signaled,
+can reduce the overall cpu usage.
