You could get the same result by preprocessing any configuration file to
remove comments and blank lines.

You don't have to reopen it for a text file any more than you do for a
DB file. Keep the file open and seek() to the beginning before the
loop. The preprocessor just has to be careful to overwrite the file in
place instead of removing or moving the old one out of the way.

DB has its own overhead, though. Since you're always scanning the file
linearly I think the overhead will be less with the text file. It's
just my instinct. If I were writing the application and the speed were
important to me I'd benchmark both approaches.
