So I'm a bit confused about how my NSOperation subclass should implement the cancel method.
Why are you overriding it? The -cancel method is not supposed to actively bring the operation to a stop. It's only supposed to set a flag. The operation's work methods (-start, -main, and whatever they call) should be periodically checking the -isCancelled property and, if it's set, gracefully bring their work to an end.
