I fail to see the benefit of using a different logging system, but I'm
ceratinly open to discuss it.

Ant's system currently is an event based system which goes beyond
simple logging and we'd still have to maintain that anyway.  It is
getting used for much more things than just logging.  AntClassLoader
uses buildFinished events to deregister and clean itself up to allow
garbage collection for example.

Vadim's stats say that cloning of the build listener list and
iterating through them are the problem, not string concatenation.

And I doubt that you could implement isDebugEnabled() at all using
Ant's BuildListener concept as the listener decides what to log, Ant
just passes the events along.  It is very well possible that one
listener will log a MSG_DEBUG message while another one will not - and
both are there at the same time.
