Sorry, I wasn't clear. I didn't mean it was weird that Linux would be able to do that. I meant I thought it was weird that a user would choose to do that. Because without any co-ordinated locking in place, or double-checking at the end (which most won't unless it's been specifically added), having one program read a file while another is modifying it will most probably produce confusing or unexpected results.
