Description:
------------
class_exists call __autoload every time on non existing classes

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

header('Content-Type: text/plain');

function __autoload($class) {
    var_dump('Autoload '.$class);
}

for($a=0; $a<10; $a++) {
    $status = class_exists('foobar');
    var_dump($status);
}

?>

Expected result:

string(15) "Autoload foobar"
bool(false)
bool(false)
bool(false)
bool(false)
bool(false)
bool(false)
bool(false)
bool(false)
bool(false)

string(15) "Autoload foobar"
bool(false)
string(15) "Autoload foobar"
bool(false)
string(15) "Autoload foobar"
bool(false)
string(15) "Autoload foobar"

That's expected. The autoload function might be non-deterministic.
