Come on give the guy a clue what the buffers do - otherwise
he'll be putting his linux box between him and the next run away
train.

Most of free memory is usually full with file system cache, so
that rather than reading a file from disk (very slow, ~10
milliseconds seek at least), it can use the copy in memory
(probably tens of microseconds).

I think we should campaign to do away with virtual memory - it
has outlived it's usefulness ;-)
