Unseting key on iterator is not an solution because in php "Array assignment always involves value copying. " So if \IteratorAggregate implementation create new iterator from array (just like [Doctrine ArrayCollection](https://github.com/doctrine/common/blob/2.3/lib/Doctrine/Common/Collections/ArrayCollection.php#L362) does)  such operation will not affect original data.

I'm just not sure if it's good to use Doctirn ArrayCollection in this test case or maybe its better to create own implementation of such Collection as a fixture.

This fixes composer/composer#2711, i.e. anyone disabling phpinfo for security (by obscurity, but whatever) reasons can not use the Process class anymore.

There is some code in the validator component which handles a PHP bug for versions strictly inferiors to 5.3.3. Since these versions are not supported (the requirements say 5.3.3 minimum) I thought we could remove it.

Regards.

[Finder] () is also a valid delimiter

The `Regex` class should also accept `()` as delimiters, as they are valid PREG delimiters: http://3v4l.org/D8v54
