Actually, it has been solved by SRA/Tatsuo. Seems Win32 commit()
doesn't actually sync all files during a checkpoint, only the _open_
files. Tatsuo's solution was to remember all files opened since the
last sync() and open/fsync each one of them to simulate sync(). I
assume I will need some of his code, but I am not there yet.
