Just a general philosophical point. Why the heck
do you care about free memory? You are like someone
who bought a preformance car but drive it at 30 mph
maximum because you don't want to wear out the engine.
I would be very worried if there is some free memory.
It will mean OS is not doing its job of caching whatever
it is supposed to be caching.
