Description:
------------
# Test setup
pm = static
pm.max_children = 1
env[testcase] = test

Refresh the page below several times...

Based on the assumption that the environment is never changed 

Test script:
---------------
<?php

if ($_SERVER['testcase'] === 'test') {
    echo 'Everything is fine; trying to break your env...';
    foreach($_SERVER as $key => &$value) {
        putenv("$key=$value");
    }
} else {
    phpinfo(INFO_ENVIRONMENT);
}
die();

Expected result:
----------------
The test script above should consistently output:

Everything is fine; trying to break your env...



Actual result:
--------------
After a few refreshes it shows the environment part of phpinfo().
