If it does, that would be fine when anydbm selects that database, but
wouldn't help people who (silently) get other databases.  Also, I believe
the shelve module always opens databases for read/write access, probably
generating unnecessary lock activity.  It would be nice if hammiefilter (at
least) could open the file read-only.
