It was alleged that certain RAID configurations can benefit by this function to 
wait for the entire rank (I think) to be ready for transfer while transferring 
with some other Rank that is ready. It gives a pseudo master/slave type of 
operation rather than the peer concept.

I wasn't around for the origins of the TARGET TRANSFER DISABLE and 
CONTINUE I/O PROCESS messages.  Am I correct in inferring that the 
primary purpose of these is to allow an initiator to temporarily suspend 
transfers from a high priority device in order to prevent bus starvation 
on low priority devices?
