Another example (mentioned by another commenter) is the Magsafe animation. Siri can be in the middle of responding to a request from my phone when I dock it to my Magsafe charger on my desk, and it obliterates the request like it never happened. Also, cannot use the phone for about 3 seconds after docking it. The green "your phone is charging!" animation takes precedence over all.
