Hi,
I'm proposing two simple patches that eliminate a lot of useless zval
copying.
For example they remove only about 800 calls to zend_hash_copy() (25%) on
each request to wordpress-3.6.0 home page and make it 2-4% faster.
It's not a questions about master branch, but I think it is also safe to
commit them into PHP-5.4 and PHP-5.5.
Any objections?
