in reply to Using DBM::Deep and Parallel::ForkManager for a generalized parallel hashmap function builder (followup to "reducing pain of parallelization with FP")

You can try replacing DBM::Deep with data serialized by Storable and shared in a simple MySQL table. You could also try sharing it via Cache::FastMmap, but be careful, since it's a cache and can silently drop data.
