I did not mean that producing the index files on the first round was
useless. It can alter the page numbers of some reference: for instance
if the index is not at the end of the document, and you refer to the
page of some chapter after it, then this page will increase after the
index file is produced.

What I meant was diffent : imagine you have to run 3 times TeX, then you
need to produce the index files only twice, not 3 times, as you don't
need them after the last TeX run. In the current implementation the
index files would be produced 3 times.

In other words, if there are N TeX runs then:
- I did *NOT* mean that you need only one index file production
- but I did mean that you need N-1 index file production.
