I think I did about the same a while ago - it definitely makes the "blinky
light" feel more correct. However, as I was reminded (and rightly so) we
also have to take into account O_DSYNC as well as proper fsync() and
fdatasync(). Nobody told me this was wrong back then, so I don't know if
<whomever> thought there was a "better way" or if they were just waiting for
the rest to be solved. *shrug* I had completely forgotten about this...
