+TargetMilestone: ---
+Summary: XmlTextReader.Close() does not close the file.
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+XmlTextReader.Close() does not close the file.
+Steps to reproduce the problem:
+1. mcs k.cs -r:System.Data
+2. mono k.exe
+using System;
+using System.IO;
+using System.Xml;
+class ReadXmlFile
+   static void Main()
+   {
+      XmlDataDocument xmlDoc = new XmlDataDocument();
+      XmlTextReader reader =
+        new XmlTextReader( "./k.xml" );
+      xmlDoc.Load( reader );
+      reader.Close();
+      xmlDoc.Save( "./k.xml" );
+   }
+<k />
+Actual Results:
+I can't write to the samed xml file that I opened and then closed 
+(supposingly) with XmlDataDocument. The same program works with .NET 
+Unhandled Exception: System.IO.IOException: Win32 IO returned 
+ATION. Path: ./k.xml
+in <0x002fa> System.IO.FileStream:.ctor 
+in <0x00043> System.IO.FileStream:.ctor 
+in <0x00081> (wrapper remoting-invoke-with-check) 
+System.IO.FileStream:.ctor (st
+in <0x0003a> System.Xml.XmlTextWriter:.ctor (string,System.Text.Encoding)
+in <0x00046> System.Xml.XmlDocument:Save (string)
+Expected Results:
+The xml file can be written successfully.
+How often does this happen? 
+Every time.
+Additional Information:
+If I call XmlDataDocument.Save() with a different file name, it is OK.
