We are aware of this. You are of course also welcome to make suggestions as to what the correct behavior in these situations should be. Thank you for trying out our new little toy! comments and suggestions are always welcome. Note 8.0 vnet support is for demonstration purposes only and we do not suggest that it be used in situations where robust behavior in the face of external or malicios agents might be a factor. i.e. it's not at all hardened (that may be an understatement).
