we have to be careful with those to make sure that no one is calling
them and then keeping the pointer around for longer than packet
lifetime.

so we have to check all the occurences of each one of them and verify
that restricting the lifetime of the returned object is never expected
to be any longer than to the end of the packet.


I dont think there are many such users  but we have to make sure.
