Description:
------------
When viewing a site (we're a large ISP with +100 domains per web server) that has include files it occasionally doesn't include the include files.

Hitting reload then brings up the proper display, file wass included.

This behaviour is on different web servers, all running 4.3.4, and very sporadic, difficult to reproduce in a consistant manner. Problem introduced since upgrading from 4.3.1

The PHP code executes fine on the file being viewed, but it misses the include occasionally. While researching this, the same behavior was noted on php.net when clicking the main documentation link.





Reproduce code:
---------------
<?PHP

include ("header.inc");
echo $HEAD;
echo "Body here";

?>

Expected result:
----------------
Header Include File Graphics
Body Here

Actual result:
--------------
Body Here
