With respect to Ralph's proposal to handle potential UA deadlock as it applies
to the basic queing model, Is it really easier for a drive to abort all tasks
on a CHECK CONDITION rather than preserving them?

Initially, I had assumed without question that an implied CLEAR TASK set was
simpler. The potential multi-initiator deadlock issue has led us in Digital to
question whether that assumption is true under the circumstances.
