Does anyone have any experience with PHP QuickHash (http://php.net/manual/en/book.quickhash.php)?

Some early testing shows massive improvements in memory usage for large arrays. An array with 1M items takes 226mb with a normal array and only 41mb with QuickHash and speed is about the same.

However I can hardly find stories from people actually using it in production environment so I'm curious to see if there are any reasons for not using it in production.
