* For the majority of things (once we have found the association) we will
* lock the actual association mutex. This will protect all the assoiciation
* level queues and streams and such. We will need to lock the socket layer
* when we stuff data up into the receiving sb_mb. I.e. we will need to do an
* extra SOCKBUF_LOCK(&so->so_rcv) even though the association is locked.
