[reSIProcate] Clean DUM shutdown

["Dominique Prunier" <dominique.prunier@xxxxxxxxxxxxxxxxxx>]

Hello,

I wonder what is the best (cleanest actually) way for shutting down the DUM.
Now, i use the shutdown(ShutdownManager) method and wait for callback but
how to be sure that the callback will be called (for exemple if it remains
some unterminated dialogs). Is there a way to terminate all the dialogs (a
cancelAll method ore something like that) or force shutting down after some
time ?

Thank you for your answer.
Regards,

Dom.
