* The clarifcation Document says in 5.8, that a IKE_SA delete should not
* be acknowledged with the same delete. This only makes sense for CHILD_SAs,
* as they are paired. IKE_SAs are not, there is only one for both ends.
*
* Normal case:
* ----------------
* Mx{D} -->
* <-- Mx{}
* Delete request is sent, and we wait for the acknowledge.
*
* Special case 1:
* ---------------
* Mx{D} -->
* <-- My{D}
* My{} -->
* <-- Mx{}
* Both initate a delete at the same time. We ack the delete, but wait for
* our delete to be acknowledged.
