Ack, what a horrible design! What happens if there's a power outage after 
the files are deleted and before the new ones are written? And why chmod 
instead of specifying the umask when the file is created? There's a 
security risk there.

The correct method should be to rename the old file, write a new file with 
the permissions copied from the old one into the open() call, then delete 
the old one.
