Indeed, they'll continue to accumulate. Chris might correct me if I'm
wrong, but I believe that caching of Z39.50 results in the reservoir
was added years ago to reduce usage of slow (and maybe even
fee-based?) Z39.50 targets; the idea is that one would search the
reservoir first, then use Z39.50 if a record couldn't be found.

The cleanup_database.pl database cronjob can be used to tidy up the
reservoir — use the --z3950 switch.
