OK ... I can do that easily; that should cause the error handler to try
with a bigger hammer.

The next problem is that this actual issue is occurring in
sas_execute_task() which takes no further action if an abort fails.  I
can easily wire in a next level ... would you recommend CLEAR_TASK_SET,
or move straight on to LOGICAL_UNIT_RESET?
