With the recent upgrade of MC in AS trunk, the "default" config on my 
system now boots in around 23 seconds consistently. Before the upgrade 
it used to take somewhere around 30 to 33 seconds.

By default aop proxies will be disabled, but can be enabled with @EnableAopProxy. Lifecycle callbacks will be enabled by default (and I'll come up with a quicker way of determining if they should apply), but can be disabled using the @DisableAopLifecycle annotation.
