/**
 * Example demonstrating an callback-based stream.
 *
 * Of particular interest in this file is that the callback actually emits
 * output; the CallbackStream implementation only allows invoking the
 * callback once, so this generally works, as you can ensure that
 * (a) the content is not double-emitted, and (b) by wrapping the callback
 * in the response, you get your headers emitted first.
