GenericTester.generic_type_expr_tester():

    Don't overwhelm the expression mechanism.  Previously, there was no delay
    between successive invocations of 'expression' command.  The test suite
    run has experienced 'Resume timed out' or similar error messages.  Now we
    currently add a sleep of 1.0 second before issuing the next 'expression'
    command.
