I haven't had time to look very closely as your more recent changes (you 
are clearly doing very good work here). The only thing I wonder if 
whether it would be possible to avoid adding to ClassLoader. I can't say 
what percentage of frameworks and applications use proxies but it would 
be nice if the impact on applications that don't use proxies is zero.
