Bug Description

When logging in in a new session or after some time of usage, the aptd daemon (and the update-manager too, presumably) will start to scan for updates.
The processes involved in this steps are usually running with full priority (or with nice values higher than 20? I wasn't able to catch it...), and this can make the system extremely slow, or even unusable on netbooks.

If possible, having these processes running at lower priority (even if only for the scanning process) would help a lot and could make the difference in systems with low performances.

Indeed aptdaemon should use a lower nice level.

Thanks for the quick reply.
I'm not sure about the amount of work that's required to fix this, but I think it's likely to be a candidate for a Papercut entry.

It needs some investigation beforehand, but the patch could be only a single line.
