instead of appending text to the file, you better append the text to the
GtkTextBuffer, and then save the GtkTextBuffer to a file once in a while.
if you need to append to the file (and not write the complete file once
in a while) I would try to append both to the file and to the
textbuffer, so you don't need to reload the entire file for every append.
