Its a problem yes, but the nature of javascript makes this a difficult problem to address. Node tried addressing this with the 'domain' module to help with propagating errors upward more generically:

But it was deprecated: https://github.com/nodejs/node/issues/66

promises are a very nice way of drying out error handling and cleaning up callbacks for now.
