@@ -7,3 +7,11 @@ teardown of the previous connection; so the new session-listener
 responds to the assertions from the old connection before the old
 connection has a chance to die. Of course, it *does* die (since commit

+   line-reader to go would be enough, but the multiple nested
+   during/spawns creating the sessions mean that no matter how long
+   the old session instance sticks around, a new session will appear
