What I also see a lot is that an inner way of a multipolygon is untagged 
and has a second way overlapping it on all nodes which is then tagged 
with the landuse of that island. This is uncessecary. The renderer is 
smart enough that you can tag inner ways with the proper landuse.
And if 2 ways overlapping is bad enough, I've seen up to 6 ways 
overlapping!

The number of items I'm deleting while cleaning this up is massive.
