-// TODO(nweiz): remove this when issue 9140 is fixed.
-/// A wrapper around [HttpServer] that swallows errors caused by requests
-/// behaving badly. This provides the following guarantees:
-///
-/// * The [SafeHttpServer.listen] onError callback will only emit server-wide
-///   errors. It will not emit errors for requests that were unparseable or
-///   where the connection was closed too soon.
-/// * [HttpResponse.done] will emit no errors.
-///
-/// The [HttpRequest] data stream can still emit errors.
