there's also the lock free "cdb+" pattern:

cdb allows 2GB for all sizes (well ... including overall file size),
is lightning fast and does not lock at all, since it's not updateable :)

However, it's a common situation to have a huge amount of keys to
look up, but only very moderate amount of updates during one day.

This can be handled easily and very efficiently by keeping
updates in memory plus streamin them out in cdbmake-format
and rebuilding the cdb during daily backup runs like
(cat change.log; cdbdump <cdb) | cdbmake cdb cdb.tmp
c.f. http://cr.yp.to/cdb/cdbmake.html

It's also very robust...
