Sure, but the machine has 8GB ram so it won't have to swap while doing 
multiple things at the same time and swapping did not take place 
(according to Munin). I'll run the script again with 5 or 6 GB heap, but 
I'm not convinced it will change the output or processing time 
significantly.

The script does a full cleanup before starting the processing. There is 
no cache directory lingering around. But I try to remember if I saw a 
cache directory while processing and I don't think I did, so maybe the 
option is already ignored.

Anyway, I've generated a pbf planet file from the bz2 XML last night, so 
can test if splitting pbf will be successful this evening.
