[zeromq-dev] [bug+workaround] socket_t not closed properly, still used

Yes. The problem with the workaround is that the creation of next socket 
could then block for indefinite time (until all the pending messages are 
sent).

So, the socket is zmq_close()'d but it takes some time to actually 
destruct it. Untill then the connection to the peer still exists and the 
peer still sends messages to the closed socket. Do I understand it right?
