True, but that doesn't mean we should be doing stupid things like trying
to open the same file twice or calling realpath() twice on the same path.
And obviously something similar is happening to the module case because we
are 10-15% slower in the module version.

The script I tested was simply:
<html>
<body>
<?
echo "Hello World";
?>
</body>
</html>
Hopefully executing this should not have caused a big change in memory
usage between 4.2 and 4.3.
