Hi Andrea,

I'm not only looking for an upgrade-solution. I'm trying to solve what
I think is a problem. In my world, ordinary users shouldn't be able to
bring a system down by exhausting all available memory. I think that
Linux is giving out to much memory to ordinary users - it should reserve
some memory solely for root in case root has to "clean up" things ...
If I am wrong, please educate me! But no flames, please ...

Kind regards,

Brian

(P.S: I think I'll try pre-7, though ... ;o)
