Not that it's relevant for the cwrap project, still my 2ct:

What's the point of SOCKET_INFO_GET_REFCOUNT? It's even more
characters in source code. Also, SOCKET_INFO_GET hides the reference
to a global variable. Why? These macros make the code harder to read,
at least for me. Macros can have their place, but what's the reasoning
here?
