Mike, after further review, if we do something like this:

   sub Log::Log4perl::appender_by_name {
	return $Log::Log4perl::Logger::APPENDER_BY_NAME{shift};
   }

then we might create problems where the user code has a reference to an
appender, then init_and_watch() reloads everything and the user's
reference is no longer connected to anything, but the user doesn't know
it.  Do you see what I mean?  Do you think this is a problem?
