+Description of Problem:
+The Application runs normally using .net framework. it crashes using Mono.
+the application uses QueueUserWorkItem function to create 56 threads that 
+do a simple counting.
+
+Steps to reproduce the problem:

+using System;
+using System.Text;
+using System.Threading;
+
+namespace ThreadPool1
+{
+	class MainClass
+	{
+
+		static void Main(string[] args)
+		{
+			for(int i = 1; i < 56; i++)
+			{
+				try
+				{
+					ThreadPool.QueueUserWorkItem(new 
+WaitCallback(StartMethod));
+				}
+				catch(Exception ex)
+				{
+					Console.WriteLine(ex.Message);
+					Console.WriteLine(ex.StackTrace);
+					Console.ReadLine();
+				}
+				Thread.Sleep(100);
+			}
+			
+			Console.ReadLine();
+		
+		}
+
+		static void StartMethod(Object stateInfo)
+		{
+			DisplayNumbers(DateTime.Now.Millisecond.ToString
+());
+			Console.WriteLine("Thread Finished");
+		}
+
+		static void DisplayNumbers(string GivenThreadName)
+		{
+			Console.WriteLine("Starting thread: " + 
+GivenThreadName);
+		
+			for (int i = 1; i <= 800; i++)
+			{
+				if (i % 100 == 0)
+				{
+					Console.WriteLine("thread: " + 
+GivenThreadName + " Count " + i);
+					Thread.Sleep(1000);
+				}
