It may be appropriate to include it in this list, but then it would be nice to make sure that the
target sends the response to the TMF first before acting on the reassigned task (which might
possibly involve retransmitting an old status sent before the connection failure with a new StatSN).
Initiators may get confused if the response for the reassigned task arrives prior to the the response
to the TMF itself (even while there are no StatSN holes).

I suggest:

For all the task management functions defined in 9.5.1, the target performs the requested function and sends a
Task Management Response back to the initiator.  In the case of the TASK REASSIGN function, the target must
send the reponse to the task management function request first before acting on the reassigned task.
