This numbers are the basis to claim that dillo2 uses half the
memory footprint of dillo1. Just check the last row or compare
the factor.
<p>
The "factor" is calculated with the RSS for the
MySQL manual (with no images), minus the empty RSS, minus 13MB,
all divided by 13MB. The memory-cached page is subtracted to get
a clean HTML-to-Widgets factor.
<p>
This is, if you have a 130KB html page, factor*130KB will be used
for rendering.
