I've got 4 cores (8 with hyperthreading) so this is something I'm acutely 
aware of. Watching my PC churn away at only 12.5% CPU for a few hours isn't 
my idea or resources well spent! Unfortunately there's no quick win because 
the XML parsing is very linear, but I have already been considering various 
options and certainly plan to give them a try at some point. I've got quite 
a few other improvements planned that'll come first though.
