- *     This fastbuf backend is intended for cases where several threads
- *     of a single program append records to a single file and while the
- *     record can mix in an arbitrary way, the bytes inside a single
- *     record must remain uninterrupted.
- *
- *     In case of files with fixed record size, we just allocate the
- *     buffer to hold a whole number of records and take advantage
- *     of the atomicity of the write() system call.
- *
- *     With variable-sized records, we need another solution: when
- *     writing a record, we keep the fastbuf in a locked state, which
- *     prevents buffer flushing (and if the buffer becomes full, we extend it),
- *     and we wait for an explicit commit operation which write()s the buffer
- *     if the free space in the buffer falls below the expected maximum record
- *     length.
- *
- *     fbatomic_open() is called with the following parameters:
- *         name - name of the file to open
- *         master - fbatomic for the master thread or NULL if it's the first open
- *         bufsize - initial buffer size
- *         record_len - record length for fixed-size records;
- *             or -(expected maximum record length) for variable-sized ones.
