SVN rev 206575 on 2010-04-14 00:50:18Z 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.
