+# Set do_close to 1 if the connection was not previously open, 0 otherwise
+# With first arguemnt including d, don't set do_close to 1.  Broadly
+# speaking, we use this mechanism to shut the connection after use
+# if the connection had been explicitly closed (i.e. didn't time out,
+# which zftp test investigates) and we are not using a directory
+# command, which implies we are looking for something so should stay open
+# for it.
+
+# Remember the old session:  zflastsession will be overwritten by
+# a successful open.
