Why not use raw C API then? The C++ API does basically nothing aside of 
converting POSIX error codes into C++ exceptions.

Because EAGAIN as returned by zmq_send and zmq_recv is not a real error 
that should be turned into exception, rather it is success status saying 
"everything is OK, but the action cannot be accomplished immediately, 
try again later".
