[Mono-list] StreamReader

I am using System.Diagnostics.Process to execute an external process.  When 
I set RedirectStandardOutput = true and attempt to read the entire stream 
either with ReadToEnd(); or looping with ReadLine(); the application freezes 
on the last read.

This happens in linux and windows so I'm assuming it's by design and I'm 
doing something wrong.

What do I need to do to read the whole stream and continue with the 

            String data;
            Process proc = new Process();
            proc.StartInfo.UseShellExecute = false;
            proc.StartInfo.CreateNoWindow = true;
            proc.StartInfo.FileName = "cmd.exe";
            proc.StartInfo.RedirectStandardInput = true;
            proc.StartInfo.RedirectStandardOutput = true;

            StreamWriter input = proc.StandardInput;
            StreamReader output = proc.StandardOutput;

            input.AutoFlush = true;
            input.Write("dir" + System.Environment.NewLine);
            data = output.ReadLine();

            while (output.EndOfStream == false)
                Debug.WriteLine("--- " + data + " ---");
                data = output.ReadLine(); 
<<-------------------------------------------------- when the last read in 
the loop occurs the program halts.

            input.Write("exit" + System.Environment.NewLine);
            data = output.ReadLine();
            Debug.WriteLine("--- " + data + " ---");
