osm2pgsql has to store nodes outside the bbox because geometries that

how certain are you regarding this?
It's only based on my observations and short comments on questions
regarding that in the IRC channels.
My germany extract import took incredibly long and the number of nodes
in the slim nodes table is around in line with the data stats for
Germany as a whole, while I only imported one city (by bounding box
filtering).
I can say it's a bug with pbf processing. I was able to reproduce the
problem and created a ticket.

I suggest you have a look at the filtering capabilities of osmconvert.
It was able to extract my desired bbox out of the 2GB asia extract
within 5 minutes.
The resulting database is now 40 times smaller and in a range I was used
to before my software upgrade.
