OK, I've determined that what looks like a memory leak is actually a caching behavior of Core Image. CIImages are cached and memory use can rise a couple of hundred megabytes before the cache is turned over. For some reason, allocating these CIImages via make-instance causes them to be cached for longer than if I allocate them with (#/imageWithData: ns:c-i-image ... or (#/initWithData: (#/alloc ns:c-i-image) ...
