If I have time, I'll open /dev/sda in emacs :). Dunno if vim can
multi-thread well enough for that type of test.
The goal is to not max out RAM or anything else for a couple of years for
this box.
In my case, the worst I'll have is a private MySQL database where the
entire contents of of the database wouldn't fill up a single stick of RAM.
I will have other things running as well, but all comparatively
lightweight compared to something that could keep two cores and 95% of the
RAM busy.
