 Could you elaborate on the difference between what you want to do and
 sparse files?

No difference. Given a non-sparse file, I want a way to make it sparse.

Well, I _have_ a way to make it sparse; all I have to do is write out a
single log entry. What I am lacking is a way for the user to tell me to do
so :)

I'm aware that you can do this by deleting the file and writing out a new
copy. But this is flash and it has a limited number of write cycles; I don't
want to do that.
