I have bad news. Today I stumbled again over the problems of the 
PolygonSplitter which left some polygons unclosed. I posted a patch for 
this which did some cody tidy around polygons and fixed this.

But I also found out that some polygons that crosses the tile border 
which are closed in the OSM data are not neccessarily closed in the 
tiles. This has to be investigated.
Does the splitter ensure that all closed ways in the OSM dump are also 
closed in the splitted tiles?

Unless this can be ensured I think it is no good to commit this patch.
