while I'm all for optimizations... and Drupal's RAM usage could 
definitely use some optimizations, the fact is RAM is fairly cheap, and 
PHP's default 8M is a bit dated. Most larger scale projects these days 
recommend 16M (in fact I heard rumours that the PHP team is considering 
up'ing the default).

I *believe* that only unset will free the memory (until the end of 
execution). i may well be wrong - so yeah, investigation is in order :)
