Hmm, merlyn's node above made me think of this: what about using Matts' DBD::SQLite in-memory database driver? It's still pre-1.0, but if it works for you, it could be a big win. You could structure your data to reduce memory hits, it supports transactions so you can control access, and it appears to have decent performance under load. There is a benchmark at SQLite vs CDB_File vs BerkeleyDB. Might be worth a try.
