OK, just to give something reproducible:

I have a set of tabs I open daily to check my comics. Those are:
http://www.gocomics.com/bloomcounty
http://www.gocomics.com/calvinandhobbes
http://www.dilbert.com/
http://www.gocomics.com/foxtrotclassics/
http://www.gocomics.com/libertymeadows
http://www.offthemark.com/daily.php/

http://safehavenscomic.com/
http://www.gocomics.com/peanuts
http://www.sheldoncomics.com/
http://www.sluggy.com/
http://ars.userfriendly.org/cartoons/

13 pages, all containing images, some of them containing several images,
some of them containing ads and other crap (although NoScript blocks
quite a bit of those). Plus Seamonkey Mail, plus the message editor
(Composer) where I'm writing this very post.

Windows Task Manager reports 326868 K for Seamonkey plus 27824 K for
plugin-container.
