  @davidedmundson - Thanks for the info!
  
  So I am thinking to do the following:
  
  1. Create a simple `ProcessList` class as @davidedmundson suggest in KF5::CoreAddon
  2. Move the `queryBlockingApps` functionality to Solid, but use the `ProcessList` implementation from KF5::CoreAddon (implement the functionality like @broulik suggests)
  3. Use the new functionality from Solid in Dolphin to show a nice end-user message
  4. Party?
  
  Does that make sense?
  
  Maybe after all this is done, use the general functionality from Solid in the Device Notifier as well? Does anyone know of other places that has the `lsof` functionality duplicated?
