Description of Problem:
System.IO.Packaging.Package.Dispose disposes the creation stream too.


using System;
using System.IO.Packaging;
using System.IO;

namespace test
{
    class MainClass
    {
        public static void Main (string[] args)
        {
            MemoryStream stream = new MemoryStream ();
            Package p = Package.Open (stream, FileMode.Create,
FileAccess.ReadWrite);
            p.Close ();
            stream.ReadByte();

        }
    }
}

throws this exception:

Unhandled Exception: System.ObjectDisposedException: The object was used after
being disposed.
  at System.IO.MemoryStream.CheckIfClosedThrowDisposed () [0x00000] in
/usr/src/packages/BUILD/mono-2.10/mcs/class/corlib/System.IO/MemoryStream.cs:133
  at System.IO.MemoryStream.ReadByte () [0x00000] in
/usr/src/packages/BUILD/mono-2.10/mcs/class/corlib/System.IO/MemoryStream.cs:261
  at test.MainClass.Main (System.String[] args) [0x00000] in <filename
unknown>:0 


the package.Close call internally makes this:

public void Close()
{
    this.Flush();
    this.Dispose(1);
}

for some reason the dispose call disposes the stream too....




Expected Results:
The stream should not be disposed and this is the behavior in .Net.

How often does this happen? 
Always.
