+Summary: IDisposable handling buggy
+
+Description of Problem:
+It seems that the Dispose method of an IDisposable object is not called
+when leaving a using() {} statement through an exception.
+
+Steps to reproduce the problem:
+1. Compile and run the following example program from "Thinking in C#":
+
+//:c05:UsingCleanup.cs
+using System;
+
+class UsingCleanup : IDisposable {
+  public static void Main(){
+    try{
+      UsingCleanup uc = new UsingCleanup();
+      using(uc){
+        throw new NotImplementedException();
+      }
+    }catch(NotImplementedException){
+       Console.WriteLine("Exception ignored");
+    }
+    Console.WriteLine("Leaving Main( )");
+  }
+
+  UsingCleanup(){
+    Console.WriteLine("Constructor called");
+  }
+
+  public void Dispose(){
+    Console.WriteLine("Dispose called");
+  }
+
+  ~UsingCleanup(){
+    Console.WriteLine("Destructor called");
+  }
+}///:~
+
+Actual Results:
+
+mono UsingCleanup.exe
+Constructor called
+Exception ignored
+Leaving Main( )
+Destructor called
+
+Expected Results: (this is what I get under MS .NET SDK)
+
+.\UsingCleanup
+Constructor called
+Dispose called
+Exception ignored
+Leaving Main( )
+Destructor called
+
+How often does this happen? 
+always.
+
