I was originally going to use berkeley db for the splitter and
if you go back to revision 3 in subversion there is
some code that uses the BerkeleyDB java edition.

I gave up on it because it seemed like it would take vastly more
disk space than the planet file and was much slower than I was expecting
or hoping.  But I didn't persevere that much before switching to
the current open hash map implementation, so I'm not saying that it is
unworkable.
