afaik, 'package-cleanup -d' lists dups only but does not remove them.

afaik, smart splits transaction into sub-transactions so that e.g.

| install A-new
| install B-new   ; B depends on A
| remove  B-old
| remove  A-old
| install C-new
| remove  C-old
| install D-new
| remove  D-new

sequences are possible. This does not remove possibility of dups
completely but reduces it significantly resp. the counts of dups.
