Node passes write and end callbacks an error argument (null on success),
but the native callbacks receive none, so an inline callback that names
the parameter read undefined. It now refuses where it is written. The
stream-shims npm case compiles now that stream subclasses are values;
its remaining scenarios are deferred refusals, so it is recorded as one.
