[Openstreetmap] duplicate track points

[Simon Hewison]

I had a thought yesterday, when I think that I forgot to clear down the 
track logs in my GPS before recording a new track.

Is there anything in the GPX upload process to eliminate duplicate 
trackpoints? exact same lat, long, timestamp and uploader is an obvious 
duplicate.

If they aren't being de-duplicated on insert, maybe a clear-up of such 
records database might make rendering the gpx wms layer a little bit 
quicker.
