The split time was reduced from 140ish (IIRC) to 102 seconds.

There seems to be something wrong with the pbf output, because mkgmap is 
outputting this kind of messages:

2011/05/19 23:53:11 WARNING (OsmBinHandler): 63240005.osm.pbf: Way 
http://www.openstreetmap.org/browse/way/107168753 references undefined

Could it be that when you delete nodes outside the output tile, you 
forget to delete the node references from the way? I have not seen these 
messages before. Or is the osm.gz output of the splitter equally broken, 
but the mkgmap XML parser is not complaining about ways referencing 
deleted nodes?

Apart from these warnings, I am still getting the warnings about 
unclosed polygons, like this:

2011/05/19 23:54:39 WARNING (StyledConverter): 63240008.osm.pbf: 
Unclosed way http://www.openstreetmap.org/browse/way/23679990 
[natural=water] should be converted as shape but the start or end point 
lies inside the bbox. Skip it.

For some reason, the pbf splitter workflow failed to issue the data 
error (one dead-end oneway) that I got reported for the same 
finland.osm.pbf when splitting it to osm.gz.

Can you fix these issues?
