I was monitoring with xrestop (on the server sudo apt-get install xrestop).  On a
running client when logged in open a terminal and run xrestop.  Then fire up firefox and
watch the memory used by firefox climb, fast, then hang.  When it freezes you can see
the last amount used before hanging.  

This appears to be due to firefox caching pixmaps to X.  We need a hack for that and the
problem should go away.  I'm using Opera in the interim.
