Brain farting here too...
What if my application variable contains a factory
that retrieves objects and then I call setters on
those objects w/o a lock?
config = application.beanFactory.getBean("baseConfig")
config.setValue("name","value")
Is this bad?
Thanks All,
Tom

Objects are passed by reference, not by value. So, you're not creating a
copy of application.ws, just a pointer to it.
That said, if you're not calling any setter methods within application.ws,
you can just dispense with the locking entirely.
