Can you experiment with WebappClassLoader instead :-) ? SCL is only used
in standalone mode and only for loading internal classes. And removing 
it will improve class loading time by itself - one less layer of if() 
and indirections.

( I'm experimenting with class loading too, and it's easier to do it in 
one loader )

What I'm trying to do is allow some modules ( connectors, auth, etc ) to 
be deployed and loaded/unloaded/upgraded at runtime.
