Right now rdiff-backup's memory requirements are basically log(n)
where n is the number of files, but this would bump it up to n.  I'm
unsure whether it would consume too much memory in practical terms..
If it takes an extra 100 bytes per file, and there are 10M files,
that's ~1GB.

Anyway, this would only improve speed and/or disk space, and from the
survey I get the impression that few people care about that.
