memory usage in mozilla

Matthew Allum and Daniel Berrange have been doing some cool work to try and figure out how much pixmap memory and system memory that Mozilla (Firefox and Epiphany) have been using. There’s a discussion on the topic on the olpc-software list. Matthew has posted some code for his server-side patches for measuing pixmap usage and Daniel has posted his analysis as well. Although this work is at a really high level, and doesn’t yet deal with what bits of code are actually causing the problems, it’s nice to see some work in this area.
