I would appreciate that, because I have to do some preprocessing (moving 
end nodes of the coastline to the tile boundary, deleting auto-generated 
bad multipolygons) after decompressing the osm file.  The sed or perl 
filter could sit between bzip2 and splitter, and all three processes 
could run in parallel.
