+Attaching a patch containing all the code implementing chained
+MulticastDelegates the MS.net-way. It doesn't work yet.
+
+I'm using following trivial test program:
+
+using System;
+class Test {
+	delegate void SomeHandler(); 
+	static void Handler1() { Console.WriteLine("Handler1"); }
+	static void Handler2() { Console.WriteLine("Handler2");}
+	static void Main() {
+		SomeHandler del_1 = new SomeHandler(Handler1);
+		del_1();
+		SomeHandler del_12 = (SomeHandler)Delegate.Combine(del_1, new
+SomeHandler(Handler2));
+		del_12();
+	}	
+}
+
+
+The resulting output should be:
+-------------------------------
+Handler1
+Handler1
+Handler2
+
+But it throws an NRE:
+---------------------
+Handler1
+
+Unhandled Exception: System.NullReferenceException: Object reference
+not set to an instance of an object
+  at (wrapper delegate-invoke) System.MulticastDelegate:invoke_void ()
+  at (wrapper delegate-invoke) System.MulticastDelegate:invoke_void ()
+  at (wrapper delegate-invoke) System.MulticastDelegate:invoke_void ()
+  at Test.Main () [0x00000]
+
+
+Could somebody take a look at my code (especially
+"mono_marshal_get_delegate_invoke" in marshal.c). It's my first
+venture into the mono runtime...
