+%% This test case should fail with timetrap timeout.
+%%
+%% The long timetrap timeout and timeout option in the expect call
+%% also causes the telnet client to hang so long that the attempt at
+%% closing it (in end_per_testcase) will time out (close timeout is 5
+%% sec) without a timetrap timeout occuring in end_per_testcase.
+%%
+%% The point is to see that the connection is thoroughly removed and
+%% unregistered anyway so that the next test case can successfully
+%% open a connection with the same name.
+%%
+%% Note!!! that if end_per_testcase reaches a timetrap timeout before
+%% the connection is closed, then the connection will survive until
+%% the hanging expect times out, after which it will be closed in a
+%% seemingly normal way due to the close message which was sent by the
+%% close attempt. This could happen any time during the subsequent
+%% test cases and cause confusion... There is however not much to do
+%% about this, except writing test cases with timetrap timeout longer
+%% than the close timeout (as this test case does)
