- Offset guest time from host time sufficiently to hide the cost of
- running in the virtual machine. This can aid the consistency of
- time between multiple timers, but can cause the guest to run
- a good bit slower than the host in VM-intensive parts of the code.

- Virtualize the processor time stamp counter in the guest,
