Right now it is probably possible using something like:    handler.acquire()    try:        handler.flush()        handler.stream = new_stream    finally:        handler.release()but it would be nice to have an officially-supported method to do that.Context: if I reconfigure sys.stderr, I'd like to update all handlers that have a reference to the old sys.stderr.

Which StreamHandler class? Is this issue related to logging? If yes, please mention it in the title ;-)

Oh, yes, sorry.  This is about logging.

How about this as an API?    def setStream(self, stream):        """        Sets the StreamHandler's stream to the specified value,        if it is different.        Returns the old stream, if the stream was changed, or None        if it wasn't.        """

Vinay, yes, that sounds fine to me.
