By itself I don't see how this is a problem.  You'll note the previous line:

       std::locale l = std::locale(os.getloc(), f);

This code is adds a facet to the existing locale, makes a copy, which then 
gets imbued into the stream.  So, all the previously existing locale settings 
should be preserved.
