* no_delay_for_missed_ticks:
* As above, missed interrupts are delivered, but guest time always tracks
* wallclock (i.e., real) time while doing so.
* no_missed_ticks_pending:
* No missed interrupts are held pending. Instead, to ensure ticks are
* delivered at some non-zero rate, if we detect missed ticks then the

* next tick period.
* one_missed_tick_pending:
* Missed interrupts are collapsed together and delivered as one 'late tick'.
