As a side note, having some method to call process_commands while idle would also fix the memory usage issues encountered when using ZMQ_CONFLATE and not reading from the socket.
https://github.com/zeromq/libzmq/issues/3171 I added documentaion to periodically call getsockopt with ZMQ_EVENTS but that still requires work on the users side.
