> This will give File Channel performance a big boost, at the cost of possible 
> data loss if a crash happens between checkpoints. 
> Also we should make it configurable, with default to false. If the user does 
> not mind slight inconsistencies, this feature can be explicitly enabled 
> through configuration. So if it is not configured, then the behavior will be 
> exactly as it is now.
