Gaak.  Yes, that's a bit excessive.  When I got to thinking about
blood sugar... I realized that I might have poo-pooed something
that was much larger than I at first thought.

Sounds like a poorly-written script to me.  You can always use
uname to limit at least some of what he can eat up... but that
really sounds like one mean script.

A loadavg of 130 means that there were at least that many
processes active... why so many?
