Using gdb, I found what is blocking after my code has finished.

Hmm. Looks interesting.
Do you have hang on zmq context termination stage?
Not sure what can I change in aiozmq but you may try zmq.Context.instance().term() after loop.close() call.

Oh, I just googled a bit and experimented another bit, and found that setting LINGER option resolves this problem.
e.g., Insertsock.transport.setsockopt(zmq.LINGER, 50) just after the create_zmq_stream() call.
It seems that the underlying TCP connection was not established (because I'm using a wrong address intentionally) and the followed write call makes the termination process of libzmq to poll availability of the TCP connection internally.

Therefore, this is not the "fault" of aiozmq at all; I'm closing the issue. :)
