To answer the question in the subject, it is safe to close a closed message--libzmq will notice that the message object is in an invalid state and report EFAULT, doing no other work.
Sending a message, however, doesn't leave it in a closed state, but a freshly-initialized one. Populating a cppzmq zmq::message_t, sending it, and then letting the dtor run at the end of scope is completely fine.
