@SaintBacchus, what is the exact behavior with this patch? Looking at the
client code it appears that is there is network issue at all it will fail and
kill the application. I don't think that is what we want here. If there is
very temporary network glitch it could kill it even though if you waited a
couple seconds it would be fine. In the very least we should have a certain
number of retries.
Also note that monitorApplication is used in both client and cluster modes.
Cluster mode nothing is running on the gateway so we don't care if it loses
network temporarily and it won't actually affect the running application so
here we would be returning something saying the application is killed when we
don't really know that.
