Well, the configuration you describe (mixing Berkeley DB versions) will
just lose because of shared library symbol conflicts, not due to any
performance reasons.

Cyrus does a LOT of enumerations of the keys of a database, which isn't as
cheap on Berkeley DB as random access.  Skiplist (and flat) are
substantially faster for enumerations.
