Summary:  Pnet does not disallowe closing streams that are connected to the 
"real" console

Original Submission:  On MS.NET, attempts to close the console device are 
ignored. By "console device," I mean output directed to a terminal. This is in 
contrast to the situation where standard output has been redirected to a file 
or pipe. To mimic MS's behavior, StreamWriters would need to check whether 
their streams correspond to "real" files or pipes or to a physical console.

The test case below succeeds on MS but fails under Pnet with the exception

Uncaught exception: System.ObjectDisposedException: Stream is already closed: 
Exception_Disposed
        at System.IO.StreamWriter.Write(String) in 
./System/IO/StreamWriter.cs:239
        at System.IO.TextWriter.WriteLine(String) in 
./System/IO/TextWriter.cs:288
        at System.IO.SyncTextWriter.WriteLine(String) in 
./System/IO/TextWriter.cs:652
        at System.Console.WriteLine(String) in ./System/Console.cs:425
        at Testing.Main()
