	* Headers accessible through annotations should always be allocated '''inside''' a packet's data (for example via push_mac_header()). Like this they get freed when the packet is killed, thus avoiding memory leaks. Yet more important is that any other tricks - for example referencing to another packet's ethernet header via annotation - lead to nasty and hard to find memory management errors. Align elements for example may shift the header annotations along with the other data of the packet which would lead to invalid addresses. Align, however is only needed on some architectures which makes detecting these things a real pain.		* Headers accessible through annotations should always be allocated '''inside''' a packet's data (for example via push_mac_header()).
