Process isolation breaks for global objects that implement the Serializable interface

[whatthejeff]

Specifying the --process-isolation flag will raise errors for global objects that implement the Serializable interface. Consider the following test:

<?php
class AClass implements Serializable {
    public function serialize() { return serialize('abc'); }
    public function unserialize($data) {}
}

$GLOBALS['A'] = new AClass;

class ATest extends PHPUnit_Framework_TestCase
{
    public function testTrue()
    {
        $this->assertTrue(true);
    }
}

Running this test with the --process-isolation flag will raise the following error:

$ phpunit --process-isolation ATest.php

There was 1 error:

1) ATest::testTrue
RuntimeException: PHP Warning:  Class __PHP_Incomplete_Class has no unserializer in - on line 79
PHP Stack trace:
PHP   1. {main}() -:0
PHP   2. unserialize() -:79


FAILURES!
Tests: 1, Assertions: 0, Errors: 1.

This happens because http://github.com/sebastianbergmann/phpunit/blob/master/PHPUnit/Framework/Process/TestCaseMethod.tpl.dist processes globals before it processes included files. For objects that implement the Serializable interface this will not work as the class declaration is needed before the object can be unserialized.
