  // 20-Mar-2009, KAB: if we get a fragment when we are not supposed to get
  // one, should we still send a discard message to the resource broker?
  // If we don't, couldn't that cause problems upstream?  If we do, though,
  // we could end up sending duplicate discard messages (one per fragment).
  // At a minimum, we should make sure that we don't try to use the discard
  // manager before it is available.
  // Of course, if we want to do this, we need to implement a way to get
  // a handle to the discard manager since outermost_context() doesn't
  // actually work here.
  //
  //if ( outermost_context().getSharedResources().get() != 0 &&
  //     outermost_context().getSharedResources()->discardManager_.get() != 0)
  //  {
  //    outermost_context().getSharedResources()->discardManager_->sendDiscardMessage(frag);
