My thoughts exactly, shouldn't be too hard for you to do.  If you need a 
hint how to get started, you subclass Log::Dispatch::Output providing 
your own log_message() method, then reference your new subclass in the 
config like this:

	log4j.appender.appndr1 = My::Buffered::Appender
	log4j.appender.appndr1.layout = Log::Log4perl::Layout...whatever
	...etc.
