350#     not specifically prepared to deal with it.  Assuming the guest
351#     OS can deal correctly with the time jump, the time in the guest

355#     will not notice anything is amiss, as from its point of view
356#     time will have continued to flow normally.  The time in the
357#     guest should now be behind the time in the host by exactly the
358#     amount of time during which ticks have been missed.
359#
360# @slew: deliver ticks at a higher rate to catch up with the missed
361#     ticks.  The guest OS will not notice anything is amiss, as from
362#     its point of view time will have continued to flow normally.
363#     Once the timer has managed to catch up with all the missing
364#     ticks, the time in the guest and in the host should match.
