Turn it off and there won't be any problems, except for missing log files here and there. But with learning on, I don't take any precautions like file locking, to prevent simultaneous updating. Which would be ugly when/if it happens... as the file will definitely become corrupted. It might just mean it leaves book earlier than it should. Or it might hang if the file gets corrupted in a different way.
