    // even though we have a single segment (which is 100% of the size of 
    // the index which is higher then our 0.6D threashold) the
    // compound ratio doesn't matter because the segment was never merged
    assertCompoundSegments(h.getCore(), expectCFS);

    assertNumSegments(h.getCore(), 1);
    // we've now forced a merge, and the MP ratio should be in play
    assertCompoundSegments(h.getCore(), false);
