> CheckpointMetricsTracker has no info about _splitAndSortCpPagesIfNeeded_ stage, thus
in case of huge number of dirty pages someone can observe in log:
> 10:08:00 checkpoint started
> 10:10:00 checkpoint finished
> <--- ?? 
> 10:10:20 checkpoint started
> if checkpointFrequency = 30000 and all tracker durations: beforeLockDuration, lockWaitDuration
gives no clue what kind of work (20 sec) Checkpointer thread is waiting for.
> Additionally (hope this is not big deal) need t obe fixed redundant effectivePageId computation
cause FullPageId already has effectivePageId info.
>  
> {{return Long.compare(PageIdUtils.effectivePageId(o1.pageId()),
>                         PageIdUtils.effectivePageId(o2.pageId()));}}
> writeCheckpointEntr() duration should also be logged.
