> 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.
