Ted: I didn't make this function cause a reboot because of _when_ this could
potentially trigger.  It could look like we'd crashed (maybe with an Android
popup saying so) and then immediately restarted Chrome.

We might want to put a temporary toast in here telling them to restart again
(non-translated, super short term, etc..)
