do you need to wait here too?

Usually you are not interested in the output of the passing test. Still, it's
probably worth unifying.

     } catch (ex) {
-      // A non-zero exit code is used by the test infrastructure to detect
-      // failure.
-      exit(1);
+      Future.wait([stdout.close(), stderr.close()]).then((_) {
+        // A non-zero exit code is used by the test infrastructure to detect
+        // failure.
+        exit(1);
+      });
     }
   }
 }
