If true, Berkeley DB flushes log writes to the backing disk
before returning from the write system call, rather than flushing
log writes explicitly in a separate system call, as necessary.

Remarks
This is only available on some systems (for example, systems supporting the IEEE/ANSI Std 1003.1 (POSIX) standard O_DSYNC flag, or systems supporting the Windows FILE_FLAG_WRITE_THROUGH flag). This flag may result in inaccurate file modification times and other file-level information for Berkeley DB log files. This flag may offer a performance increase on some systems and a performance decrease on others.
