If you're saying that it shouldn't call fsync automatically I'll agree
to that.  The message thread I was replying to seemed to say that
tempfiles didn't need to support fsync because they will be useless
after a system crash.  I'm just refuting that by showing that it is
useful to call fsync on tempfiles as one of the steps in preserving the
data in another file.
