That would make sense.

(1) dodgy DBD (DBD::AnyData, I hate you so much ...)

(2) because the way Ima::DBI uses it, it'll recycle a live sth you'd hung onto
    because you weren't finished fetching data from it, thus screwing your app
    up quite spectactularly. It only works for CDBI because CDBI fetches all
    the data from the sth straight off and throws it away.
