not quite correct: the SUB socket could still be connected to several 
other PUB sockets.The abort is still present when you modify the test case accordingly.

it is not unexpected, as zmq_poll indicates that the SUB socket has data.

>>> It is a so bad news. I would like to use the disconnect routine to discard messages in 'REQ/REP' and 'PUSH/PULL' mode.As blow:socket s = socket.create(PULL)s.connect(addr1)s.recv(msg)s.disconnect
s.connect(addr2)s.recv(msg)           // there may have dirty messages according to your theory.
