I didn't consider it no...

What I'm currently attempting is first retrieving the size of the file
via fstat; and never attempt to read more than what the file is...

But reading the manpage of fdatasync, in our scenario, it shouldn't
make a difference as the file size *is* modified...

it more and more smell like a linux filesystem handling issue; and
we're just trying to find a way around the problem
