+# when mosh isn't installed on the server, but tmux is, use this to get a
+# fairly persistent set of remote shell sessions.  I used to use autossh here,
+# but that means surprise dialogs asking to authorise use of an SSH key;
+# instead, just hit <Ret> to restart a window's connection when it's
+# convenient
+#
+# (The reason that I get prompted is because I have a short
+# ServerAliveInterval and low ServerAliveCountMax, but that's desirable,
+# because unresponsive SSH sessions are a massive pain)
