I don't think that is true, because when I run Windows XP as a guest in 
qemu, the qemu process doesn't use 100% CPU unless something is actually 
running in Windows.

I suspect that Andreas gets 100% CPU usage with a FreeDOS guest because 
FreeDOS doesn't do CPU idle... that's not how DOS works.  It's not much 
of an operating system at all, really.
