Which can take 100% of a core on a multi-core system while still
allowing X and other processes to execute on the other core...
Still, though, a dual-core that's slower-enough than a single-core will
be worse than the single-core. (Figuring out the value of
"slower-enough" for any given processor (at any given speed) is an
exercise left to the reader.)
