I think you're blaming the wrong module (LWP).  When I take HTML::Parse out of the game, I don't get any leakage.

OTOH, when using just HTML::Parse, I see it leaking, too.

use HTML::Parse;

while(1) {
    parse_html('');

    system "ps -p $$ -o rss,vsz";
    sleep 1;
}

(Not that this makes much difference from an end user perspective... but you now at least know what to file a bug report against.)

The usual workaround for long running programs with memory leaks is to fork a new worker process every n iterations.
