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)
bool(false)

Actual result:
--------------
string(15) "Autoload foobar"
bool(false)
string(15) "Autoload foobar"
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.
