Re^3: memory usage on x86

The only thing that came to mind that might account for the difference was if something was being statically rather than dynamically linked. Could that still apply to one of the indirect components?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?

No, I don't think so.
