+Summary: System.Timers.Timer doesn't work properly when using the SynchronizingObject property
+
+Description of Problem:
+System.Timers.Timer doesn't work properly when using the
+SynchronizingObject property.
+
+
+Steps to reproduce the problem:
+1. Compile the following sample code using
+   mcs stt.cs /r:System.Windows.Forms.dll
+
+using System;
+using System.Reflection;
+using System.Security;
+using System.Security.Permissions;
+using System.Timers;
+using System.Windows.Forms;
+
+class Program {
+
+	static void ShowStackTrace (object o, ElapsedEventArgs e)
+	{
+		Console.WriteLine (counter);
+		if (counter++ > 5) {
+			t.AutoReset = false;
+			t.Enabled = false;
+		}
+	}
+
+	static System.Timers.Timer t;
+	static int counter = 0;
+
+	static void Main (string[] args)
+	{
+		bool so = (args.Length > 0);
+		Label label = new Label ();
+
+		t = new System.Timers.Timer (500);
+		if (so)
+			t.SynchronizingObject = label;
+		t.Elapsed += new ElapsedEventHandler (ShowStackTrace);
+		t.AutoReset = true;
+		t.Enabled = true;
+		
+		System.Threading.Thread.Sleep (5000);
+	}
+}
+
+
+
+2. Execute the compiled assembly without parameters
+
+   mono stt.exe
+
+3. Execute the compiled assembly with a "x" parameter
+
+   mono stt.exe x
+
+
+Actual Results (Mono):
+
+% mono stt.exe
+0
+1
+2
+3
+4
+5
+6
+
+% mono stt.exe x
+
+[... nothing happens ... nothing returns ...]
+
+
+Expected Results (MS):
+
+% mono stt.exe
+0
+1
+2
+3
+4
+5
+6
+
+% mono stt.exe x
+0
+1
+2
+3
+4
+5
+6
+
+
+How often does this happen? 
+Always
+
+
+Additional Information:
+Some debugging code inside corlib shows that AsyncResult are being
+allocated at each interval. However the callback isn't executed.
