I think it’s clearer to write:


But I’m not sure anyone else in this project agrees with me!

Also, I think that Ryosuke said our overall strategy is to protect differently

function protecting itself. So the fix would be in
RemoteMediaResourceManager::loadFinished, which should be using a RefPtr for
its local variable.
