>
> Inside Replica::persist(const Action& action), we update the in-memory 
> 'holes' data structure
>   // Update holes if we just wrote many positions past the last end.
>   for (uint64_t position = end + 1; position < action.position(); position++) 
> {
>     holes.insert(position);
>   }
> During catch-up (starts with an empty log), if the 'position' is very large, 
> we may spend a lot of time in this loop. Also, the data structure 'holes' 
> might become extremely large.
