Is this still right?

Nope.  Fixed.

+import "dart:sky.internals" as internals;
+
+class _SkyConfig extends SimpleConfiguration {
+  void onDone(bool success) {
+    try {
+      super.onDone(success);
+    } catch (ex) {
+      print(ex.toString());
+    }
+
+    internals.notifyTestComplete("DONE");
+  }
+}
+
+final _singleton = new _SkyConfig();
+
+void initUnit() {
+  unittestConfiguration = _singleton;
+}
