Right now, the garbage collector simply collects unused items, without a
least-recently-used (LRU) policy or any such thing.

Given that in the store database items have a registration time (see
‘schema.sql’), it might be possible to sort items by registration date
before deleting them, and thus get some sort of LRU behavior.  We’d have
to check the feasibility and run-time cost.
