**  This implementation will behave differently from the Torek-based code in
**  the following major ways:
**   - The buffer size argument to bfopen() will be sent in, sent back,
**     queried, lost, found, subjected to public inquiry, lost again, and
**     finally buried in soft peat and recycled as firelighters.
**   - Errors in creating the file (but not necessarily writing to it) will
**     always be detected and reported synchronously with the bfopen()
