I know of a few people. They are very good at multitasking and increasing performance on renders in supporting apps (like LightWave, Cinema4D, Maya, 3DSMax, ...). With two 2.66GHz HT-enabled Xeons, I can render a scene in 2 minutes that would take a single non-HT processor 20 minutes or more. Or start a render in Poser 5 and get my email/surf the web/continue working on the model in C4D with no loss of performance in either. I agree that not many people have multiprocessors, but they are becoming more frequent (e.g.: Apple PowerMac G5's). Also, I'll revise my last message and state that HT support would be even more excellent. HT-enabled processors are definitely more ubiquitous - any P4 2.4GHz and greater, IIRC. Believe me, there is nothing more "hi-demand job" than 3D rendering. All rendering is done in the main CPU, none in the GPU. Rendering animations is so time consuming that most (who can afford it) sublet the work to render farms using dozens or hundreds of computers so that time-consumption is lowered back to reality. Even my three computers, two dual-processing, would be overburdened to do any quality animation rendering of any sufficient length.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
