* Here we give server socket a buf_sock purely because it is difficult to

* of structs at the moment. However, this doesn't have to be the case in
* the future. We can choose to wrap different types in a common header-
* one that contains a type field and a pointer to the actual struct, or
* define common fields, like how posix sockaddr structs are used.
