I read it in the node documentation, as did the OP, where the exact quote is reproduced. It specifically is on the docs page for domains: http://nodejs.org/api/domain.html#domain_warning_don_t_ignore_errors.
It's the most prominent instruction we have regarding how to handle thrown errors, and it says to kill the process completely (in the context of that page, use domains and cluster to kill the worker process and spin up a new one). That's great, and is the right approach in many situations, but it's not universal. It's perhaps not much publicized when you might want to use a simple try/catch to continue on without worry because, according to nodejitsu (http://docs.nodejitsu.com/articles/errors/what-is-try-catch) the only place in node core we really use it is the example I gave, JSON.parse(). But inherent in that example are the reasons why you generally want to take more care and why, in some simpler situations, you may not need to. As I said, my main point is that the warning, as stated, doesn't really provided a basis for learning why and, subsequently, intelligently using and handling errors.
