Top should not say "free", it should say "wasted"...  A small free
memory pool is kept to satisfy allocations, and the rest of the memory
holds cached copies of data that has recently been read from or written
to disc, as mentioned elsewhere in this thread...

 People who interview themselves shouldn't criticize writing styles.
