patch 8.0.1245: when WaitFor() has a wrong expression it just waits a second

Problem:    When WaitFor() has a wrong expression it just waits a second,
            which goes unnoticed. (James McCoy)
Solution:   When WaitFor() times out throw an exception.  Fix places where the
            expression was wrong.
