[Registry-dev] Needing a context for Registry

[Sanjiva Weerawarana]

If we do end up doing this, then rather than system props the better way 
to pass the registry context around would be using thread local storage. 
Then we'd get at it by saying RegistryContext.getCurrent() or something 
like that.
