HUGE Virtual Memory Usage

[Matt Patterson]

I was just wondering if this is a normal thing. I have a machine with 
768 megs ram, but the VM numbers given by System Monitor seem 
outrageous. Right now in the VM column I see:

firefox-bin    232.1 mb
soffice.bin    208.8 mb
nautilus         176.7 mb
gnome-vfs-daemon   52.7 mb
gnome-terminal      50.7 mb
X     220.4 mb
mozilla-thunderbird   152.2 mb
vmware-vmx   317.3

That alone says 1.3 gig of memory which should basically fill all my 
mem/swap. What gives with this description?
