Should we share the save session / pref?

[gone, 2012/12/21 19:19:00]

An earlier version of this CL actually had that code uncommented out, but it
ended up pulling a bunch of other code that we've never linked.  I'm not
entirely clear on what that code is supposed to do given that we don't normally
run it when Chrome dies on Android, but I'll dig.

 void AttemptRestart() {
   // TODO(beng): Can this use ProfileManager::GetLoadedProfiles instead?
   BrowserList::const_iterator it;
   for (it = BrowserList::begin(); it != BrowserList::end(); ++it)
     content::BrowserContext::SaveSessionState((*it)->profile());
 
   PrefService* pref_service = g_browser_process->local_state();
   pref_service->SetBoolean(prefs::kWasRestarted, true);
 
 #if defined(OS_CHROMEOS)
   // For CrOS instead of browser restart (which is not supported) perform a full
   // sign out. Session will be only restored if user has that setting set.
   // Same session restore behavior happens in case of full restart after update.
   AttemptUserExit();
 #else
   // Set the flag to restore state after the restart.
   pref_service->SetBoolean(prefs::kRestartLastSessionOnShutdown, true);
   AttemptExit();
 #endif
 }
+#endif
 
 #if defined(OS_WIN)
 void AttemptRestartWithModeSwitch() {
   // The kRestartSwitchMode preference does not exists for Windows 7 and older
   // operating systems so there is no need for OS version check.
   PrefService* prefs = g_browser_process->local_state();
   prefs->SetBoolean(prefs::kRestartSwitchMode, true);
   browser::AttemptRestart();
 }
