Hmm, this does not happen to my fedora core 2 box. It raises
file sharing error. Which version of mono are you using?

When you open a file via XmlTextReader, it is locked until you
explicitly call Close(). Thus, the file sharing error should be
thrown, since you are keeping the file opened.

Once you read up the source xml into XmlDocument, the input file can
be used (by calling Close()).

In which culture are you living? The line below will provide you the
exact information.

Console.WriteLine (System.Globalization.CultureInfo.CurrentCulture);

We could not support all the culture and it may differ if IBM icu
defines different culture data. Right now CultureInfo.InvariantCulture
should work fine.

Maybe you are in different culture when you are using those machines.
