+Summary: Random crashes recently.
+
+Recently mcs/tests/test-105.cs started crashing randomly, I include it here.
+
+using System;
+using System.Threading;
+using System.Runtime.InteropServices;
+
+class Test {
+	delegate int SimpleDelegate (int a);
+
+	static int F (int a) {
+		Console.WriteLine ("Test.F from delegate: " + a);
+		Thread.Sleep (200);
+		return a;
+	}
+
+	static void async_callback (IAsyncResult ar)
+	{
+		Console.WriteLine ("Async Callback " + ar.AsyncState);
+	}
+	
+	static int Main () {
+		SimpleDelegate d = new SimpleDelegate (F);
+		AsyncCallback ac = new AsyncCallback (async_callback);
+		string state1 = "STATE1";
+		string state2 = "STATE2";
+		string state3 = "STATE3";
+		string state4 = "STATE4";
+		int fin = 0;
+		
+		IAsyncResult ar1 = d.BeginInvoke (1, ac, state1);
+		IAsyncResult ar2 = d.BeginInvoke (2, ac, state2);
+		IAsyncResult ar3 = d.BeginInvoke (3, ac, state3);
+		IAsyncResult ar4 = d.BeginInvoke (4, ac, state4);
+		
+		int res = d.EndInvoke (ar1);
+
+		Console.WriteLine ("Result = " + res);
+		try {
+			d.EndInvoke (ar1);
+		} catch (InvalidOperationException) {
+			Console.WriteLine ("cant execute EndInvoke twice ... OK");
+		}
+
+		ar1.AsyncWaitHandle.WaitOne ();
+		if (ar1.IsCompleted) fin++;
+		Console.WriteLine ("completed1: " + ar1.IsCompleted);
+		ar2.AsyncWaitHandle.WaitOne ();
+		if (ar2.IsCompleted) fin++;
+		Console.WriteLine ("completed2: " + ar2.IsCompleted);
+		ar3.AsyncWaitHandle.WaitOne ();
+		if (ar3.IsCompleted) fin++;
+		Console.WriteLine ("completed3: " + ar3.IsCompleted);
+		ar4.AsyncWaitHandle.WaitOne ();		
+		if (ar4.IsCompleted) fin++;
+		Console.WriteLine ("completed4: " + ar4.IsCompleted);
+
+		if (fin != 4)
+			return 1;
+		
+		return 0;
