+Summary: Regression: ObjectDisposedException when calling XmlTextWriter.Close() twice
+
+Recent modifications made to XmlTextWriter, changed the behaviour when the
+XmlTextWriter is closed.
+
+When invoking Close() on an XmlTextWriter the underlying StreamWriter is
+now both Flushed and Closed,  While only Close should be called. When
+StreamWriter.Close() is called, a flush will be performed anyway.
+
+As a side-effect of calling both Close and Flush on the StreamWriter, an
+ObjectDisposedException is thrown when calling Close twice on the
+XmlTextWriter (as the Flush call will throw an ObjectDisposedException the
+second time).
+
+When you compile and execute the following code :
+
+using System.IO;
+using System.Text;
+using System.Xml;
+
+public class EntryPoint {
+  public static void Main() {
+    XmlTextWriter writer = new XmlTextWriter("test.xml", Encoding.UTF8);  
+                
+    writer.Close();
+    writer.Close();
+  }
+}
+
+The following exception is thrown on Mono :
+
+Unhandled Exception: System.ObjectDisposedException: The object was used
+after being disposed.
+in <0x00035> System.IO.StreamWriter:Flush ()
+in <0x0001c> System.Xml.XmlTextWriter:Close ()
+in <0x0004a> EntryPoint:Main ()
+
+Running the same code on MS.NET works fine.
