6. GdsConnection.Disconnect()

the XdrStreams - send and receive must be disposed, but can not becouse it has been GC supressed,

in Disconnect we can GC.ReRegisterForFinalize disposed objects

public void Disconnect()
{
try
{
if (this.receive != null)
{
GC.ReRegisterForFinalize(this.receive);
this.receive.Close();
this.receive.Dispose();
}
if (this.send != null)
{
GC.ReRegisterForFinalize(this.send);
this.send.Close();
this.send.Dispose();
}
if (this.networkStream != null)
{
this.networkStream.Close();
}
if (this.socket != null)
{
this.socket.Close();
}

this.receive = null;
this.send = null;
this.socket = null;
this.networkStream = null;
}
catch (IOException)
{
throw;
}
}

These streams are not in 2.5 trunk.
