Below is a snapshot of the 48 hour running window
    of graphs generated by the enhanced tellerstats
    shell scripts.  This particular snapshot was chosen
    to demonstrate a small experiment.  Note the huge
    spikes in the system load average plot.  They were
    generated with a script that compiles the Linux 2.6.7
    kernel in a loop, with the commands

        make -j3 MAKE='make =j3' clean;\
        make -j3 MAKE='make =j3' bzlilo;\
        make -j3 MAKE='make =j3' modules

    The effect was to keep the load average above 8
    for more than 30 minutes.  The effects (or lack of
    them) on system voltages and temperatures is
    visible in the resulting graphs.

    (A new graph, generated October 3rd, and unrelated
    to the others, has been added.  The graph shows 5 inside
    and 3 outside temperature probes and data generated via
    a Crystalfontz CFA-633 device.)
