This is mainly a Berkeley-specific question:
http://www.sleepycat.com/docs/ref/am_misc/dbsizes.html

The default page size used by libldbm is 4096 bytes, which gives you 2^44
(16 terabytes) as the maximum database size. If you need more, you can
redefine the DEFAULT_DB_PAGE_SIZE macro and recompile libldbm. I doubt
that you'll need to do this any time soon.

Oh damn, maybe I should have deleted this instead of replying...
