The Gnus registry would be well suited to use sqlite directly, though -- it's basically hand-maintaining a (large) database, and sqlite is a good fit for that. That is, I don't think the new normal persistence method would be ideal for the registry. But, yes, the Gnus registry is a good demonstration of why serialising hash tables to disk is unworkable in practice. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
