Irrespective to use of multicast, the termination sequence goes like this:

1. Thread A closes all its sockets and invokes zmq_term.
2. zmq_term blocks
3. Other threads will get ETERM error when invoking any 0mq function 
afterwards.
4. They should close all their sockets and terminate.
5. When all the sockets are closed and there are no more data to send, 
zmq_term unblock and original thread is free to terminate.
