I don't think thread-safe TagLib is a particularly good idea. It would
cause too many speed penalties for no good reason. I definitely want
to be able to call different instances of TagLib classes from
different threads though. I believe that fixing the RefCounter should
be the only thing that is needed. The other static instances are
read-only, as far as I remember.
