// - nsServiceManager

// - nsRegistry
//
// Here are key points to remember:
// - A global of all these need to exist. nsServiceManager is an independent object.
// nsComponentManager uses both the globalServiceManager and its own registry.
//
// - A static object of both the nsComponentManager and nsServiceManager
// are in use. Hence InitXPCOM() gets triggered from both
// NS_GetGlobale{Service/Component}Manager() calls.
//
// - There exists no global Registry. Registry can be created from the component manager.
