fastcgi_finish_request() does not always work
<p>I need to delay some hard operations, so i'm using fastcgi_finish_request()</p>

<pre><code>echo "Test";
fastcgi_finish_request();
sleep(10);
</code></pre>

<p>Generally, it works, but if i have a lot of queries (several per second), i noticed that after 5-6 queries they begin to take too long time (from 4 to 6 seconds) to execute. 
What is the reason for that?</p>
