> Ok, I could implemented the wraparound event as a periodic timer and the
match events are kicked off as seperate one-shot timers when the wrap
around occurs? There would still be a small delay on match events, but it
would get rid of the integration effect of lots of little delays (over many
wrap arounds) add up to a significant skew.
