Hello Robert, the issue is that ldconfig scans all C libraries which
change their atime and mark them as used. At least that used to be the
case, I did not check recently. However note that the popcon server
compensate for that by marking all dependencies of a 'recently used'
packages as also 'recently used'.

I would be grateful If you investigated whether this is still relevant.

I will deal with the /proc/*/maps issue.
