This isn't new for 2.1. I think you are just getting lucky on that other code.
The problem is this line:
> @socket = ZMQ::Context.new.socket(ZMQ::UPSTREAM)
You are not saving a reference to the context that you just created, so the GC
will reap it at some point. Change it to:
> @context = ZMQ::Context.new
> @socket = @context.socket(ZMQ::UPSTREAM)
And now all will be well with the world.
