Description:
------------
It seems in PHP6 (from CVS), virtual() doesn't work, well not the way it used to if zlib.output_compression = On

In fact, as soon as the virtual request is called, the remaining output's after that call are also not sent to the browser.

However, apache access logs say that they served correct amount of bytes.

Setting zlib.output_compression = Off makes it work just fine.

Reproduce code:
---------------
pointless.txt:
 Hello World 

virtual.php
<?php
echo "I can see this\n";
virtual('pointless.txt');
echo "\nBut not this";

Expected result:
----------------
I can see this
Hello World
But not this

Actual result:
--------------
I can see this
