Description:
------------
In Symfony2, there are two front controllers, app_dev.php 
and app.php which assumes as index via htaccess. When apc 
3.1.7 (cgi mode) is enabled both controllers the output is 
the same. Say the dev controller is requested first, the 
prod controller will also show the debug toolbar which is 
disabled in prod. If prod is requested first the prod will 
not show the debug toolbar.

Environment (apache 2.2 modfcgi):
https://gist.github.com/915486

Also tried this versions (pierre's builds)
apc-igbinary-fastlz-snap20110301-5.3-ts-vc9-x86
php_apc-3.1.8-dev+igbinary-1.1.2-dev-20110321-5.3-ts-vc9-x86

And nginx 0.8 + apc also shows the same bug

Have not tested via mod_php in apache.




Reproduce code:
---------------
1. Download and install Symfony2 PR10
2. Enable apc 3.1.7
3. request http://symfony-se/ (prod)
4. request http://symfony-se/app_dev.php (dev)

Expected result:
----------------
prod must not show debug toolbar
dev must show debug toolbar

Actual result:
--------------
prod has no debug toolbar
dev has no debug toolbar
