The intial import went all right on 8.3 and 8.4; my "4 times slower" was 
about adding a daily diff to the data base. The node changes were 
reasonably fast, and then it took ages to process the way changes. I 
think I'll instrument osm2pgsql to produce intermediate timestamps for 
the various steps.
