And I bet they are doing the same thing, too. NOT!

Then what does it do? If there is only 3 megs free, and my process wants to 
allocate 4 megs, what happens?

And your programs are all well-behaved and used the proper memory classes in 
allocation requests. Now quite a few don't, so you have to disable Gigamem
for them (GM comes with a list of such programs). What happens when VM kicked
in, you still have 20M swap space free, but all your physical memory has been
comitted already, and now one of these non-VM aware programs requests 20k?
