Description
When performing certain kinds of tasks within a Linux guest (in this instance specifically Gentoo) certain types of tasks cause the system CPU utilization to jump to very high levels, typicall >70% and often >90%. This seems most pronounced when doing things within portage that run shell scripts or python scripts. I am using the current guest additions. I have tried HZ at 100 and 1000. With and without apic, with and without smp. I get somewhat better performance with preemption set to server instead of the desktop models.

Problem continues in 3.0.x (through 3.0.4). However, the ability to use multiple CPUs alleviates part of the problem.
