It seems to me that test8-vm3 handles this fine. in test9 upon loading X i was
already using swap and down to 10MB ... here i have netscape loaded and some other
stuff along with gaim and i've got 36MB free still. I'm not so sure you can chalk
this up totally to X .... test9 is a VERY VERY poor kernel compared to test8-vm3
