> Things to think about 
>  * Commit time has to be unique across writers 
>  * Parallel writers can finish commits out of order i.e c2 commits before c1.
>  * MOR log blocks fence uncommited data.. 
>  * Cleaner should loudly complain if it cannot finish cleaning up partial writes.  
>  * Move the pending rollback work into cleaner
>  
> P.S: think about what is left for the general thing : log files may have different order, inserts may violate uniqueness constraint
