this test might be redundant with v2_spawn_function_test.dart. If we want to
keep it, we should rename this file to spawn_function_test.dart, since 'spawn'
alone is not descriptive enough anymore.


Related to this. I think we should remove the 'v2_' prefix from all the other
isolate test files.

I have removed this test. It is redundant with the other spawn_function test. I
have removed the v2 prefixes.

 #import("dart:isolate");
 #import('../../lib/unittest/unittest.dart');
 
 main() {
   test("spawn a new isolate", () {
-    SpawnedIsolate isolate = new SpawnedIsolate();
-    isolate.spawn().then(expectAsync1((SendPort port) {
-      port.call(42).then(expectAsync1((message) {
-        Expect.equals(42, message);
-      }));
+    SendPort port = spawnFunction(entry);
+    port.call(42).then(expectAsync1((message) {
+      Expect.equals(42, message);
     }));
   });
 }
 
-class SpawnedIsolate extends Isolate {
-
-  SpawnedIsolate() : super() { }
-
-  void main() {
-    this.port.receive((message, SendPort replyTo) {
-      Expect.equals(42, message);
-      replyTo.send(42, null);
-      this.port.close();
-    });
-  }
-
+void entry() {
+  port.receive((message, SendPort replyTo) {
+    Expect.equals(42, message);
+    replyTo.send(42, null);
+    port.close();
+  });
 }
