Thank you for reporting this.

I'll implement some backup scheme similar to what you propose as soon as 
possible. Maybe it should be controlled by an option and disabled by 
default, given that the current method is more efficient and seems to be 
safe enough (no complaints in 14 years).


Best regards,
