[OSM-dev] Duplicates in planet.osm

While processing osm files, I'm finding lots of duplicates. For instance,
all seem to be the same (high)way, created by the same user "Branco".
I've deleted all but one, as they're just duplicates, but I'm finding
this kind of problem surprisingly often, in many different countries.
I'm only noticing the problem when there are more than 20 (!)
duplicates of a given road, but I'm certain that these duplicates are
happening more often and are just slipping under my radar.
1) Where is this coming from? Overzealous users not understanding how
to use Potlatch (IIRC, it's always and only Potlatch) or maybe
inputting gps tracks multiple times?
2) What can be done to catch and eliminate all these duplicate ways?
