  SVN rev 197452 on 2009-09-24 08:35:17Z by attilio
  
  MFC r197445:
  Let fall down in the hard path (thus handling shared waiters wakeup
  correctly) for the shared waiters also in the rwlock held in shared mode
  as well, fixing possible deadlocks.
  
  Please note that this is a special condition as we want this fix in
  before RC2 as we assume it is critical and so it has been handled
  as an instant-merge.  For the STABLE_7 branch, 1 week before the MFC
  is assumed.
