DbgkInitialize()
 -> ObjectTypeInitializer.ValidAccessMask = DEBUG_OBJECT_WAIT_STATE_CHANGE;
 -> ObCreateObjectType(&Name,&ObjectTypeInitializer,NULL,&DbgkDebugObjectType);

DbgUiConnectToDbg()
 -> NtCreateDebugObject()
  -> ObCreateObject(...,DbgkDebugObjectType,...)

CreateProcessInternalW()

 -> NtCreateProcess(..., hDebug,...)
  -> PspCreateProcess(..., hDebug, ...)
   -> ObReferenceObjectByHandle(DebugPort, DEBUG_OBJECT_ADD_REMOVE_PROCESS,..)
    -> fails!
