Boy. A diff would show it although I am not sure
I cna provide this for Pavel in the meantime. The main
thing is that the calculation around $measure[] was just
plain wrong, not retaining and rotating the value. There
is a if ($DEBUG) around there ... Also, I remember that
there was a pipe-like logic which would block for us
and not give results on SL 3.0.2 ...

The values themselves do not matter much. Correlated
or not, the final formula is rather arbitrary (user's choice)
and Andy made this flexiblke enough that you may or may not
use it at the end.

While I beleive we have a if -e /proc/meminfo
ready to be epxanded for other OS as otherwise, pgio=0.
So, an imoprovement to the initial script while not perfect.
I hope you agree on the positive.
