Hmm, running more than four threads on a four core machine is a bit 
useless... all the context switches will just slow it down.

Sun have a CPU with eight cores, where each core can run eight hardware 
threads. That means, 64 hardware threads. Yea! But they are only good 
for integer stuff, so no luck for rendering.

Which brings me to the question: how many floating point units does the 
Xeon have per CPU?
