Comment #9 on issue 641 by jprantan: Dialog library keyword hangs when
timeouts are used on Windows with Python
http://code.google.com/p/robotframework/issues/detail?id=641
Actually this fails also with Python Thread so it seems that the problem is
not in our threading code. Tried to change the tkinter code without
success. So there is no ideas what is causing the problem.
Implemented mechanism to discover if the timeout is used and fail the test
execution with information that Dialogs library cannot be used with
timeouts on Windows with Python. Implementation r4103 and test updates
r4104.
