+Subject: [PATCH] High: executor: fix regression in remote node shutdown
+
+This reverts the essential part of d61494347, which was based on misdiagnosing
+a remote node shutdown issue. Initially, it was thought that a "TLS server
+session ended" log just after a remote node requested shutdown indicated that
+the proxy connection coincidentally dropped at that moment. It actually is the
+routine stopping of accepting new proxy connections, and existing when that
+happens makes the remote node exit immediately without waiting for the
+all-clear from the cluster.
+
+Fixes T361
