You're right, using that file to create a big piece of data was just for demonstration purposes. In my personal case it's XML parsing. The way I read what you just said is that this is behavior by design. But if I don't throw Exceptions, memory usage stays constant. Throwing and catching these exceptions are the exception-to-the-rule.
Nonetheless, if this is truly by design.. maybe that's something to look into for PHP6.
