      Implement what I described here:

              if ( _impossible ) {
            // TODO We might want to allow this dummy table scan even in no table
            // scan mode, since it won't scan anything.
            if ( _frs.nNontrivialRanges() )
                checkTableScanAllowed( _frs.ns() );
            return shared_ptr<Cursor>( new BasicCursor( DiskLoc() ) );
        }

      Also audit additional notablescan functionality (see SERVER-2222).
