I was recently using the version prior to this, had collected a 21MB database with around 5K hashes of 6 elements each. I found I was utterly unable to iterate over the values in the database after awhile and had to completely throw away my database. I was running out of memory on a machine with almost no load and 1GB of RAM! It would be good to include a program that can read your databases without requiring DBM::Deep for purposes of data recovery. I'm now very, very leery of ever using this database. It seems like a one-way trip.
