That doesn't prove a thing. I tried HTML::TreeBuilder on a 15k HTML
file, on a PC (DOS Perl), and I got an out of memory error, with many
megabytes available for Perl.

This HTML parsing seems to be very memory hungry. My guess is that this
is because every HTML tag is a not so small object in memory. A lot of
those objects, and you're quickly out of memory.

Just give an acceptable proof that there IS indeed a memory leak, e.g.
by parsing the same file over and over again, clearing memory (=
releasing objects) every time, and watching it get out of memory after
many loops.
