Ok, thanks for the explanation. 

That might be an issue in my program as I'm using a lot of hash tables
(Perl habits ;). I still need to determine if those hash tables are
influenced by external output, in current and next design. Or I might
drop those hash tables in favor of more suitable data structures for
performance and security reason. I've not yet considered performance
issues.

Any way, many thanks Thomas and Richard for your explanations.

And thank you also Yutaka for your initial comments.

Yours,
david
