Portability I would wager. And portability with as much efficiency as possible. I guess the current streams implementation requires him to perform a lot of low level emulation to get past perceived deficiencies in the stream handling architecture. Not every Joe has the luxury of installing extensions and so often a PHP script can provide the widest possible audience.
