I'm trying to tell you what you have to say to move forward on this issue:

1) tell people that they are mistaken about drives ignoring the FUA bit or
   flush cache
2) convince people that the performance benefit of request barriers is
   worth it

I think we all care, but when we actually care--when money depends on it--
we adopt other measures scsi, batter backed raid, etc.
