I think it's the kernel's speed consideration to not move stuff around
from disk without need. When those other app's procs wanna run again,
the hardware will need them back in RAM so they'll all slowly return
while the buffer space is given up. No use to force it, if it's done
on demand. Well, atleast in theory :)
Now, how my Linux manages to go into 2MB swap, with 160MB physical RAM,
70MB of them in buffers is still a mystery to me ... yet another
optimization consideration? :)
