Who complains about a 30MB memory usage increase these days? Who even notices? 
This is not Mac OS 9, it doesn't matter what your app's memory footprint is 
(within reason).

I expect Core Image is caching stuff for future use - blurs for example are 
expensive to set up. Might be worth comparing the time taken to execute the 
first time this is called with subsequent times - if there's a worthwhile speed 
up you can claim it as a feature - classic speed vs. memory tradeoff.
