The problem has been "corrected enough" for there to be no need to
reindex, AFAIK.

I think what Tom is concerned about is that this hasn't been tested
enough with big datasets.  Also there a little loss of index pages but
it's much less (orders of magnitude, I think) than what was before.
This is because the index won't shrink "vertically".
