Dear Maintainer,
When unattended upgrade runs it is using up 100% CPU for half an hour:

I see no reason why it is eating up so many system resources, especially
because this is only the control process it is not even
downloading/unpacking/installing anything on its own, except pooly designed
algorythms.
This behaviour is especially bad on battery powered devices.
regards
Hans
