On reboot, [Mem: free] and [-/+ buffers/cache: free] will both be large.
As apps claim memory, both will fall. As apps access files and more data
becomes cached, [Mem: free] falls. If the apps don't do much disk I/O,
then it wont reach near zero. If and when it reaches near zero, it will
remain that way until reboot.
