In fact it isn't (anymore).

I've seen modern hardware run buildworld for days, but explode on
scientific FP work in a few minutes.

It used to be the case that buildworld would stress a CPU, but with
all the specialty circuitry put into CPUs these days, buildworld
probably ends up using the MMX and SSE extension silicon as a
heatsink.

A real stress-test would be something which engages bus-interface,
integer, floating point and preferably any "extensions" as well.
