A dba_popen() handle outlives the request, but flatfile kept the buffer of the last returned key, inifile its current and last-fetched lines, and cdb_make its hash list in it as emalloc'd memory, which the next request or the close at shutdown then freed or read. flatfile now frees the key right away and uses its file position as the iteration marker; inifile and cdb_make allocate what they keep with the persistence of the handle.

There are frankly bigger problems with DBA persistent handlers considering |
