It makes you sound arrogant and passive-aggressive. Even if the other side is &lt;i&gt;totally&lt;/i&gt; wrong, hammering that fact in is rhetorically counter-productive.</text></comment>

Most notably, it causes fsync() to actually act like sync(), so flushing a single file to disk can potentially cause a flush of the entire disk buffer instead!</text></comment>
