The caveat is that goofys is subjected to the underly S3, which if you are using Amazon is only eventually consistent (http://areweconsistentyet.com/)
Reading around[1], it looks like close-to-open consistency means that all writes must be flushed before the close() call returns, and all subsequent open() calls to the file must see the changes. IO may otherwise be buffered or cached by the FS.
