+# XXX this test intermittently fails, at this client...
+# the client gets a 451 rcpt-v fail for userd3
+# the stderr-server says it got a conn-refused for the verify callout, which should have
+# gone to the above "server" command, first of the 2 conns it is expecting
+# the stdout-server shows "server" handling the previous subtest (userd, userd2) fine, plus
+# a fresh "server" startup and listen. Which should have been this one... perhaps it was
+# not there in time? Add server-wait synch point for _previous_ server, using dummy "exim -z".
