I'm not completely sure, but muy guts say that this would not be a problem.
If your program crashes (or is shut down) and there are buffers that are not
written yet, then the file will miss this information, but will not get
corrupted.

The only problem may appear if you shut down the program *during* a write
process. In that case I guess you will end with a corrupted file, as there
are no provision of I/O transactions yet.
