Yeah, makes sense. But IO::Dir don't have a sync() method. So how am I
supposed to do what Ted Ts'o is recommending?

I am talking about perl's posix(3pm) manpage. The real posix standards
would hardly talk about IO::Handle, would they?

And it's not only posix(3pm) saying that fsync is deprecated. When I try to
use perl's fsync, it also tells me to use IO::Handle instead.
