   // This really belongs in platform code, but there's no good place to

   // (where there's no profile) and the time the controller gets another
   // crack at the start of the main event loop. By that time,
   // StartupBrowserCreator has already created the browser window, and it's too
   // late: we need the pref to be already initialized. Doing it here also saves
   // us from having to hard-code pref registration in the several unit tests
   // that use this preference.
