Garanteed order for child messages

[pjuza]

When new asynchronous child message is created then it has identical msgTimestamp as parent message. There is SQL query for garanteed order where you can find "ORDER BY m.msgTimestamp".
From this is not clear which message (parent or child) will be processed firstly - if first is parent message then child message won't be processed anymore, if first is child message then it will be ok.
