How did you arrive at this notion?

From four considerations:

It did not show up in any of the tests.
To use it, you have to use "bare" file descriptors; this is relatively un-pythonic.
To use it, you have to worry about data getting on the disk - this really requires some kind of expert application.
It is not universally available, so the expert application I had to assume in 3) would most likely test for presence of fsync, and fall back to just not use it (and perhaps invoke sync(1) instead).
