+Subject: [PATCH] Properly handle EOF condition on libkrad sockets
+
+In the previous code, when the remote peer performed an orderly shutdown
+on the socket, libkrad would enter a state in which all future requests
+timed out.  Instead, if the peer shuts down its socket, we need to
+attempt to reopen it.
