I tried calling release on the NSTextView and DisposeControl on the HICocoaView but neither actually dispose of the instance because dealloc is never invoked. I suspect this is because of the retain count being what it is.

Do not look at -retainCount. It gives you no useful information. If
you want to make sure you're correctly balancing retains and releases,
use the static analyzer and Instruments.

That's not an accurate description of how the event dispatch works.
