> A timer pool's tick starts at t0 (zero). Once the first period has passed,
> the timer pool is scanned for any timers that have expired since t0 + 1.
> Current code does an atomic fetch increment on the tick, but uses the
> previous tick during timer expiration processing. What is needed is the
> previous tick + 1.
> The observable effect without this patch is that timers are expired one
> period (timer resolution) later than they should be.
