This is a "hard problem" in any case - emulation or no emulation.

But with todays multicore + hyperthreading CPUs you can do so on a 
coarse "1 CPU core" granularity. I.e. a Nehalem quad-core CPU will 
present itself as 8 logical CPUs and you can bind processes to these 
logical CPUs to achive 1/8 granularity (possibly with jails, or any 
other virtualization).
