+Summary:  Problem closing Streams
+
+Hello:
+
+
+I´m making test of the Firebird ADO.NET provider on linux Red Hat 8.0 with
+the latest sources of mono, i have a problem, I have BinaryReader used for
+reading data sent by the server, and a BinaryWriter for send data to the
+server created as:
+
+    db.Output = new XdrOutputStream(new
+BufferedStream((System.IO.Stream)db.DbNetworkStream));
+    
+    db.Input  = new XdrInputStream(new
+BufferedStream((System.IO.Stream)db.DbNetworkStream));
+
+
+When i disconnect from a database i make:
+
+    db.Input.Close();
+    db.Output.Close();  // Here gives an exception
+    db.DbNetworkStream.Close();
+    ...
+
+
+This works well on Ms .Net, and it has been working well on old versions of
+mono (0.17).
+
+
+
+The exception is:
+
+Unhandled Exception: System.ObjectDisposedException: The object was used
+after being disposed
