> If you take {{libuv_recv}} example C program and set up a "server" with

> then {{libuv_recv}} does not quit even after I kill the "server" with ^C  (which should close the socket). This happens with all C example receivers. It does not happen with {{examples/python/simple_recv}}, which just disconnects and then keeps trying to reconnect. I am not sure if the disconnect behavior is just missing from the C clients (in that case it is not a big deal) or if it gets stuck somewhere deeper in proton-c (in which case it may actually impact someone).
