> If message delivery is delayed enough, it's possible for a framework not to receive its FrameworkRegisteredMessage (with ID "A") before its (one second) timer to resend its RegisterFrameworkMessage (as part of reliable registration). The master will happily register the same framework PID again with a different framework ID (with ID "B"). The framework will receive offers for both ID "A" and ID "B", but will reply to offers as ID "B", causing the framework to CHECK()-fail when it checks the validity of the offers.
