+Summary: System.Threading.Timer.Dispose fails
+
+Description of Problem:
+According to the MSDN entry about IDisposable, "If an object's Dispose
+method is called more than once, the object must ignore all calls after the
+first one." Mono's Timer doesn't conform.
+
+Steps to reproduce the problem:
+using System.Threading;
+class Test {
+	static void Main() {
+		Timer t = new Timer(Callback);
+		t.Dispose();
+		t.Dispose();
+	}
+	static void Callback(object o) {}
+}
+
+Actual Results:
+System.NullReferenceException
+
+Expected Results:
+silent termination
+
+How often does this happen?
