Unused memory is wasted memory.

linux keeps buffers and caches of previously used apps just in case they are
needed again and so greatly increases loading and access speed and reduces
disk access.

If the memory is required it is released almost instantly, the delay is far
outweighed by the slowness of disk reads/writes.
