> 
> The secondary processes are not allowed to release shared resources.
> Only process-private ressources should be freed in a secondary process.
> Most of the time, there is no process-private ressource, so the close
> operation is just forbidden in a secondary process.
> 
> After adding proper check in the port close functions, some redundant
> checks in the device remove functions are dropped.
