Sure, sorry if my comment can be treated in this way ... I mean surprising amount of people I've met criticised Linux (well, some years ago when DOS was popular) that he/she want to see that 'free memory' field reported eg by 'top' should be the maximum all the time ... I mean this way: this is the behaviour which is quite wrong, I've written about this.
