that the Stage1 Initialization of dependent active namespaces must complete

inter-namespace subscriptions can be put in place before event providers

are activated in any one of them. Enforcing that all stage1 initialization

of dependent active namespaces does not cause a problem of all namespaces

being doomed by one faulty class provider in any single namespace because
|
|
stage1 init is guaranteed not to access any providers. All stage2 init of

|
dependent active namespace, which may access providers, is performed

asynchronously.
