motherboard:  SiS-661GX
CPU:          Intel(R) Pentium(R) 4 CPU 2.53GHz

Compiling ruby, in particular.  (I can't get RVM to integrate with tk 
properly, so have recompiled a bit.)  Also, for some reason thunderbird 
pegs the CPU when downloading messages.  Plus, the odd flash website 
(flash is such a hog it's absurd).  Generally, the CPU is at ten percent 
or so, or even less.

Since it's a single-core, regular type, old CPU I don't think the 
hardware is capable of the throttling you mention, though.
