[IronPython] Embedded IronPython 2.6 Module Name

[jhoward at drawloop.com]

Thanks, that gives me at least something.  Any idea why:

    ss.Engine.Execute("__name__", ss);

returns "<module>" but:

    ss.Engine.CreateScriptSourceFromString("__name__",
SourceCodeKind.Expression).Execute(ss);

returns "__main__"?
