  SVN rev 206576 on 2010-04-14 01:09:14Z by yongari
  
  MFC r206364:
    Partial revert r204545.
    Just relying on status LE ownership of status block seems to cause
    poor performance. Always read current status index register first
    and then check status ownership as we had before. Accessing status
    index register seems to trigger immediate status update if
    controller have pending status updates.
