 The above patch is not good at performance because of exception 
 handling. A bit better way is to try to cast Stream as FileStream 
 (hopefully once in the construction phase), and if it relly is, then 
 check CanSeek and skip this check.

+Ok, friend of mine just did an expariment on Windows. he steped into
+the code of StreamReader when the method is called. It does not *ever*
+have a call to .Position. In fact, the only method call was
+Encoding.GetDecoder ().
+So I think the impl of DiscardBufferedData is not meant to update the
+position in the stream.
