This is why you should stick to one thread for one problem. Read my
reply on your original thread. You cannot safely update intermediate
lines in a text file unless you're positive they're the same length.
And even then, using seek() to position yourself is fraught with
problems, especially if you have to work on Windows.
Either use a binary file, or write the whole file out each time.
