Julian,

iSCSI targets are already allowed to originate Async Messages. This is not
a new procedure being proposed.

This does not communicate to the initiator the reason for the connection 
close. It is better to use an Async Message for this purpose than 
abruptly terminate the connection, for the same reason that one would 
rather use a Lgout than close a connection. [in the case where a Logout 
is sent on the same connection that is being cleaned up.]
