I can load an Archived (or Initializing) Space by using its OID

(Bug, To be Fixed , Priority: High, Test Status: No automated tests yet , Reported By Justin du Coeur, )
System
Summary: The Archive mechanism only prevents loading the Space by name; it still loads fine by OID, and it shouldn't.
This is a serious problem for the new Import architecture -- we need to ensure that no other copy is loaded while we are in StatusInitializing. If somebody opens it separately and manages to make changes during initialization, it could corrupt the Space permanently.
