The Cinema4D demo works on all cores as expected; I can't find any other
programs which display this problem.

Running WoW, I can see several threads in top, but only one of them shows any
activity. I've tried running a CPU intensive addon, but still one thread does
all the work. I wonder if maybe the sound thread uses a lot of CPU under
Windows but a negligible amount under Wine? Sounds unlikely, especially since I
have hardware sound turned off to prevent lockups in Alterac Valley.

I can't understand why the game would spawn extra threads and not use them.
Maybe it's using some fragile threadpool system that for some reason can't tell
that it would be a good idea to start farming out work to the extra threads.

TBH without knowing more about the game's internals I'm utterly at a loss as to
how to explain or reproduce this behaviour so, since it is playable, I think
I'll have to give up on this for now.
