I think the problem is people come into zeromq expecting a high level library that handles all the details, zeromq does not do that, you need to handle reliability and disconnect behavior yourself. I agree that the default behavior in this case could be saner, but it's pretty easy to build reliable request reply in many different ways as illustrated in the guide, so I'm fine with it. The benefit though, is that in zeromq you get to (and are forced to) choose exactly how your messaging patterns are reliable (or not)
