I was using CVS head but given Tom's explanation I wouldn't expect to see any
different behaviour here.

I just retried it and it did block. I can't think of anything I could have
done wrong last time to make it appear not to block. If I had missed an error
at some point along the way I would have expected the reindex to complete
quickly or fail or something but it was definitely just blocked. I remember
noting (much) later that it had finished.

Strange.
