Yah, the SMP stuff works the same in a vkernel as it does in a real
kernel. If anything, the vkernel is even more sensitive to conflicts
since vkernel 'cpus' are threads on the real system and can wind up
being scheduled as time-share (for example, booting a 4-cpu vkernel
on a single-cpu platform).
